Hey @Daimona, testing on https://test.wikipedia.org/wiki/Special:EventDetails/195, here's what I see in the console:

error in expose login TypeError: Cannot read properties of undefined (reading 'getId')

at exposeLoginInDOM (VM1009 contentScript.bundle.js:106:26)
at VM1009 contentScript.bundle.js:143:11

[CdxPopover]: The "anchor" prop must be provided to position the CdxPopover.

The stream mediawiki.client.session_tick is out of sample. No event will be sent

Yeah, these seem to be all from other components. Ideally they shouldn't be there, but none of them seems to be from our code.

FYI, this file is not visible because it's not attached to the task.

No longer seeing this.

[CdxPopover]: The "anchor" prop must be provided to position the CdxPopover.

That is T405025 (CheckUser-UserInfoCard).

That is T416058 (Test Kitchen).

Closing, as the original issue was resolved.
