Error "Request textDocument/documentSymbol failed" appears regularly #446

Closed tchajed closed 11 months ago

tchajed commented 11 months ago

While typing out code (so with many intermediate states with invalid code, and possibly due to concurrency) I very often get this error:

[Error - 12:00:38 PM] Request textDocument/documentSymbol failed.
Error: Illegal argument: line must be non-negative

I'm using v3.2.1 of the extension and Dafny v4.3.0, and I'm on macOS.

Any chance you could post a piece of code that causes this? I'm guessing it's a deterministic error.

Sure, open up a new Dafny file and type function, then wait for a second.

Thank you! Fixed on master now
