Definition for rule was not found

Hi there, sorry to bother with this, but I’m running into an issue, only when building, in this public repo.

The issue is with disabling an eslint rule concerning a line. For now, I can just use // eslint-disable-next-line, but I don’t like that because I lose the information of what exactly I’m trying to disable on that line. The file in question is here on line 22. (For now I just have an additional comment above the line, noting what I am disabling, please don’t mind that.)

The error I’m getting when building is:

Definition for rule 'functional/immutable-data' was not found  functional/immutable-data

There is a place in my code where I have to mutate some data. Of course, not an issue, so I added

// eslint-disable-next-line functional/immutable-data

Above the line I needed to skip. That worked fine, the error went away in my vscode “problems” pane just like I expected it to.

The thing is, when building, the error showed up and stopped the build. Strange…

The .eslintrc.js is here. The tsconfig.json is here.

If anyone has any ideas or pointers I’d really appreciate it. Thank you.

Here’s a minimal example that exhibits the problem. https://github.com/DylanRJohnston/async-workshop/tree/f2e1d106dfaf06f8fbbeb26aaef69e654bb0d397
