Error with @typescript-eslint on project inside sym-linked folder

Due to company policies, on my machine, my home directory (cd ~) points to /users/<username>, and /users is a symbolic link to /home. When I open a folder in VS Code located under /users, every TS file I open has the following ESLint error at the top:

Parsing error: "parserOptions.project" has been set for @typescript-eslint/parser.
The file does not match your project config: ../../../../users/<username>/path-to-project/path-to/file.ts.
The file must be included in at least one of the projects provided.

When I open the same folder but from /home instead of /users, the error message disappears and the extension works as expected, which confirms that my project’s TypeScript and linting configurations are correct (i.e. parserOptions.project points to the project’s tsconfig.json, and the files on which the error appears are properly included by this tsconfig.json).

This issue has already been reported in the @typescript-eslint repo: https://github.com/typescript-eslint/typescript-eslint/issues/2234, but the fact that it works fine when running ESLint from the command line, seems to point to the vscode-eslint extension as the culprit (which probably explains why the issue was closed without being resolved).

It is not a blocker, obviously, since I’m able to open my projects from /home instead of /users, but I think it’s worth investigating given that it took me a few frustrating hours before I was able to identify the root cause. I hope this issue can save other people from experiencing this frustration.

OK. I did some additional tests that the problem only occurs when sym-linking in the root (e.g. users - home). Since the same problem shows up in the terminal when validating an absolute file I would say it is a problem of the @typescript-eslint/parser when they do path math to locate the file.

I also tried relative paths in the extension however that resulted in the same problem with root symlinked folders.

I recommend that you open an issue against @typescript-eslint/parser

Please ping if there is anything else you think I need to do.

In the case above /users is a symlink to /home
