## Summary
Found in 7.9.0, if you post a rule with an action that has a missing "meta" then you are going to get errors in your UI that look something like:
```ts
An error occurred during rule execution: message: "Cannot read property 'kibana_siem_app_url' of null"
name: "Unusual Windows Remote User" id: "1cc27e7e-d7c7-4f6a-b918-8c272fc6b1a3"
rule id: "1781d055-5c66-4adf-9e93-fc0fa69550c9" signals index: ".siem-signals-default"
```
This fixes the accidental referencing of the null/undefined property and adds both integration and unit tests in that area of code.
If you have an action id handy you can manually test this by editing the json file of:
```ts
test_cases/queries/action_without_meta.json
```
to have your action id and then posting it like so:
```ts
./post_rule.sh ./rules/test_cases/queries/action_without_meta.json
```

## Summary
**Current behavior:**
- **Scenario 1:** User is in the exceptions viewer flow, they select to edit an exception item, but the list the item is associated with has since been deleted (let's say by another user) - a user is able to open modal to edit exception item and on save, an error toaster shows but no information is given to the user to indicate the issue.
- **Scenario 2:** User exports rules from space 'X' and imports into space 'Y'. The exception lists associated with their newly imported rules do not exist in space 'Y' - a user goes to add an exception item and gets a modal with an error, unable to add any exceptions.
- **Workaround:** current workaround exists only via API - user would need to remove the exception list from their rule via API
**New behavior:**
- **Scenario 1:** User is still able to oped edit modal, but on save they see an error explaining that the associated exception list does not exist and prompts them to remove the exception list --> now they're able to add exceptions to their rule
- **Scenario 2:** User navigates to exceptions after importing their rule, tries to add exception, modal pops up with error informing them that they need to remove association to missing exception list, button prompts them to do so --> now can continue adding exceptions to rule

## Summary
Before this PR you can see event loop block times of:
```ts
formatIndexFields: 7986.884ms
```
After this PR you will see event loop block times of:
```ts
formatIndexFields: 85.012ms
```
within the file:
```ts
x-pack/plugins/security_solution/server/lib/index_fields/elasticsearch_adapter.ts
```
For the GraphQL query of `SourceQuery`/`IndexFields`
This also fixes the issue of `unknown` being returned to the front end by removing code that is no longer functioning as it was intended. Ensure during testing of this PR that blank/default and non exist indexes within `securitySolution:defaultIndex` still work as expected.
Before, notice the `unknown` instead of the `filebeat-*`:

An explanation of how to see the block times for before and after
---
For perf testing you first add timed testing to the file:
```ts
x-pack/plugins/security_solution/server/lib/index_fields/elasticsearch_adapter.ts
```
Before this PR, around lines 42:
```ts
console.time('formatIndexFields'); // <--- start timer
const fields = formatIndexFields(
responsesIndexFields,
Object.keys(indexesAliasIndices) as IndexAlias[]
);
console.timeEnd('formatIndexFields'); // <--- outputs the end timer
return fields;
```
After this PR, around lines 42:
```ts
console.time('formatIndexFields'); // <--- start timer
const fields = await formatIndexFields(responsesIndexFields, indices);
console.timeEnd('formatIndexFields'); // <--- outputs the end timer
return fields;
```
And then reload the security solutions application web page here:
```
http://localhost:5601/app/security/timelines/default
```
Be sure to load it _twice_ for testing as NodeJS will sometimes report better numbers the second time as it does optimizations after the first time it encounters some code paths.
You will begin to see numbers similar to this before this PR:
```ts
formatIndexFields: 2553.279ms
```
This indicates that it is blocking the event loop for ~2.5 seconds befofe this fix. If you add additional indexes to your `securitySolution:defaultIndex` indexes that have additional fields then this amount will increase exponentially. For developers using our test servers I created two other indexes called delme-1 and delme-2 with additional mappings you can add like below
```ts
apm-*-transaction*, auditbeat-*, endgame-*, filebeat-*, logs-*, packetbeat-*, winlogbeat-*, delme-1, delme-2
```
<img width="980" alt="Screen Shot 2020-08-21 at 8 21 50 PM" src="https://user-images.githubusercontent.com/1151048/90949142-211ffa00-e403-11ea-8ab2-f66de977dce3.png">
Then you are going to see times approaching 8 seconds of blocking the event loop like so:
```ts
formatIndexFields: 7986.884ms
```
After this fix on the first pass unoptimized it will report
```ts
formatIndexFields: 373.082ms
```
Then after it optimizes the code paths on a second page load it will report
```ts
formatIndexFields: 84.304ms
```

Restore the resolverTest plugin. This will allow us to run the test plugin and try out Resolver using our mock data access layers. Eventually this could be expanded to support multiple different data access layers. It could even be expanded to allow us to control the data access layer via the browser. Another option: we could export the APIs from the server and use those in this test plugin.
We eventually expect other plugins to use Resolver. This test plugin could allow us to test Resolver via the FTR (separately of the Security Solution.)
This would also be useful for writing tests than use the FTR but which are essentially unit tests. For example: taking screenshots, using the mouse to zoom/pan.
Start using: `yarn start --plugin-path x-pack/test/plugin_functional/plugins/resolver_test/`
## Summary
Assert unreachable was created through advice given by both the Typescript community and through the techniques that TyepScript is trying to achieve type safety with switch statements.
This fixes recent bugs by:
* Re-adding the never type
* Reduces the two different types by putting the helper within the common section so there's not duplication
* Fixes on type that looks like it was a regular string rather than a one of the enum types
The reasoning for exhaustive checks within switch statements and techniques can be seen in numerous areas such as here:
https://stackoverflow.com/questions/39419170/how-do-i-check-that-a-switch-block-is-exhaustive-in-typescript
You can do it either way with TypeScript as long as you ensure you have a explicit return type and you do early return statements you can actually avoid having to call into the assertUnreachable.
If introduced and used correctly it is there to help out like this error it is telling us that this string type is not exhaustive:
<img width="921" alt="Screen Shot 2020-08-24 at 10 39 42 AM" src="https://user-images.githubusercontent.com/1151048/91075618-9b1ad380-e5fb-11ea-9200-1c355faf5dca.png">
You can notice that for this pull request I actually remove the assertion like so if someone accidentally removes one of the switch statements:
<img width="1014" alt="Screen Shot 2020-08-24 at 10 42 08 AM" src="https://user-images.githubusercontent.com/1151048/91075662-a968ef80-e5fb-11ea-8d74-a92eedd63892.png">
And since the function has an explicit return type it is not needed. You will see that TypeScript improved its never types behind the scenes where it actually will tell you that it will never reach the `assertUnreachable` and want to remove it as an auto-refactor. That is ok as long as we have explicit return types and what I did with one line of code here.
<img width="536" alt="Screen Shot 2020-08-24 at 11 21 05 AM" src="https://user-images.githubusercontent.com/1151048/91075861-efbe4e80-e5fb-11ea-9991-dda111a04f1d.png">
Without this fix, and having the never type become an unknown it introduces less safety where any code that is utilizing the assertUnknown without explicit return types will be prone to having run time errors being thrown when something new is added to their switch enum types.

Since routing key figures fairly prominently throughout PagerDuty APIs,
and ours, it seems like it make sense to include it in the single validation
message we have for it, as well as using the term we use for it in the product:
"integration key".

The release manager is currently expecting a Docker asset image with
the format of `kibana-8.0.0-SNAPSHOT-docker-image.tar.gz`. If this
target is not found, it will re-export the image. Making this change to
produce the expected filename will remove that duplicated effort.
Additionally, the release manager plans to remove this fallback in the
future anyways.

* [Setup] Change error connecting status code to 502
- For clearer error handling
* Set up new HttpProvider/Logic Kea store & listeners
- This allows us to:
- connect() directly to HttpLogic in other Kea logic files that need to make http calls, instead of passing in http manually via args
- Set http interceptors & remove them interceptors on unmount within Kea
- Share state derived from http (e.g. errorConnecting, readOnlyMode) between both AS & WS (but allow each app to handle that state differently if needed)
+ Refactors necessary for these changes:
- Kea types - add events key, clarify that mount returns an unmount function, fix reducer state type
- ReactDOM unmount - remove resetContext({}), was preventing logic from unmounting properly
* Update AS & WS to show error connecting component at app level
* [WS] Remove errorConnecting logic & http arg from Overview
- Since main app is now handling errorConnecting
- http can now be connected directly from HttpLogic Kea store, so no need to pass it
+ minor cleanup in logic_overview.test.ts - remove unneeded unmount(), act(), switch to HttpLogic mock
* [AS] Add top-level ErrorConnecting component & remove error logic from EngineOverview
* [AS] Clean up/move EngineOverview child components into subfolder
- delete old ErrorState component
- move LoadingState, EmptyState, and EngineOverviewHeader into subfolders in engine_overview
* PR feedback: Update test assertions 404 copy
