We're migrating to ESM, which will allow us to import the latest
versions of our dependencies.
Co-Authored-By: Christopher Kolstad <chriswk@getunleash.io>
As part of preparation for ESM and node/TSC updates, this PR will make
Unleash build with strictNullChecks set to true, since that's what's in
our tsconfig file. Hence, this PR also removes the `--strictNullChecks
false` flag in our compile tasks in package.json.
TL;DR - Clean up your code rather than turning off compiler security
features :)
https://linear.app/unleash/issue/2-2453/validate-patched-data-against-schema
This adds schema validation to patched data, fixing potential issues of
patching data to an invalid state.
This can be easily reproduced by patching a strategy constraints to be
an object (invalid), instead of an array (valid):
```sh
curl -X 'PATCH' \
'http://localhost:4242/api/admin/projects/default/features/test/environments/development/strategies/8cb3fec6-c40a-45f7-8be0-138c5aaa5263' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '[
{
"path": "/constraints",
"op": "replace",
"from": "/constraints",
"value": {}
}
]'
```
Unleash will accept this because there's no validation that the patched
data actually looks like a proper strategy, and we'll start seeing
Unleash errors due to the invalid state.
This PR adapts some of our existing logic in the way we handle
validation errors to support any dynamic object. This way we can perform
schema validation with any object and still get the benefits of our
existing validation error handling.
This PR also takes the liberty to expose the full instancePath as
propertyName, instead of only the path's last section. We believe this
has more upsides than downsides, especially now that we support the
validation of any type of object.

I've tried to use/add the audit info to all events I could see/find.
This makes this PR necessarily huge, because we do store quite a few
events.
I realise it might not be complete yet, but tests
run green, and I think we now have a pattern to follow for other events.
### What
Adds `createdByUserId` to all events exposed by unleash. In addition
this PR updates all tests and usages of the methods in this codebase to
include the required number.
