TS module not found until server is restarted

[connor4312]

In VS Code, using the workspace TS version (5.6.0-dev.20240618)

1. Create a new TS file
2. Try to import an existing module
3. Get a "not found" error until you restart the TS language server

Seems to work fine for me. Can you try collecting the TS Server log:

1. Set "typescript.tsserver.log": "verbose",
2. Restart VS Code and reproduce the problem (try doing a minimal number of steps to keep the log small)
3. In VS Code, run the TypeScript: Open TS Server log command

That should help us understand what's going on

I created a file called another.ts and imported labelForTestInState. TS created the auto-import but the import had the same "module not found" diagnostic.

Thanks @connor4312

IN the logs, I can see that another.ts ends up in the inferred project instead of the main project:

Do you happen to know if this was a recent regression? Did you test on a previous version?

[connor4312]

I have seen this happen before, but I think it's been a while (a few releases at least.)

Unfortunately I don't have intellicode installed

I deleted my previous comment just after posting because the issue was actually not resolved and the error where not showing during my tests for some other random reason.

But great news, I actually found a new solution which is to disable the enableProjectDiagnostics option. -> microsoft/vscode#168410

settings.json:

"typescript.tsserver.experimental.enableProjectDiagnostics": false,

That's unfortunate because now only opened files report error, but that's still better than having random errors on every new files.

I think this is fixed by #59625. Please provide repro and log and open a new issue if its not fixed.
