Additional context

I was using Magic Racket pretty happily for a while.
Now it has started popping up this error every time I type something in my current file.
I don't think there is a syntax error in the file as it runs fine outside VS Code (and even if there was I would not want this intrusive error).
I have restarted VS Code but it's still happening.

---

If relevant, please enclose a minimal example file which triggers the errors. If you're unable to enclose the file, please do the following instead:

1. Enable logging in Magic Racket's settings.
2. Restart VS Code.
3. Open the problematic file.
4. Trigger the error.
5. Copy the whole log from Output > Racket Language Server into some text file and enclose it to your bug report.

It's not a minimal example unfortunately, but this is the file which seems to be a problem:
https://github.com/anentropic/rkt-write-thru-hash/blob/e497eeea70221c85129c368a03a5dae04d6ae682/tests.rkt

Thanks for reporting, I'm very short on time at the moment, but I'll test it out ASAP.

[benrbray]

I'm having the same issue. I'm working through the Beautiful Racket Stacker Tutorial and even the most basic examples fail with the error above.

@benrbray I think your issue might be caused by not having the #lang on the first line in the file. Of course, that’s a bug, but it should be repoerted in the langserver repo instead. I’ll look into it and report it there if my guess is confirmed.

[benrbray]

I just tested again with the first line omitted -- unfortunately I get the same error.

Thanks for making this extension! Looking forward to using it once I get past this issue.

[Eugleo]

Thanks for checking! Then it will be some custom-lang induced error, I need to check (probably it'll still go to the langserver repo).

[silesky]

@Eugleo To follow up: I get the same error as @benrbray when doing the br tutorial, regardless of what line number the lang declaration is on. I mentioned it in: jeapostrophe/racket-langserver#12.

[patrickhluo]

I get the same error every time, and I found that some predicates are not in the suggested function. Btw I tried every language, advanced student, intermidiate, beginning, every one, it just doesn't work

[battleunicorn]

I am experiencing the same issue described above. I am on windows if it helps.

[Runi-c]

Every issue mentioned in this thread has been fixed over at the langserver in jeapostrophe/racket-langserver#51, jeapostrophe/racket-langserver#38, & jeapostrophe/racket-langserver#53 (once it's merged)

Update your racket-langserver!

Closing this issue. Reopen if the issue persists after updating once the PR is merged.
