[Error - 9:42:06 AM] Request textDocument/definition failed.
  Message: InternalError: panic handling request textDocument/definition: bad line number. Line: 65, lineMap length: 33
  Code: -32603

Steps to reproduce

I couldn't easily reproduce again. I was commenting out some code and then it appeared to error when the editor lost focus. I tried re-doing edits and it didn't occur.

The file I am in has 44 lines so not sure where bad line number 65 or line map length 33 came from.

Checking the LSP logs:

[Trace - 9:42:06 AM] Sending request 'textDocument/definition - (54)'.
Params: {
    "textDocument": {
        "uri": "file:///c%3A/Projects/a/b/c.play.ts"
    },
    "position": {
        "line": 65,
        "character": 24
    }
}


[Trace - 9:42:06 AM] Received response 'textDocument/definition - (54)' in 1ms. Request failed: InternalError: panic handling request textDocument/definition: bad line number. Line: 65, lineMap length: 33 (-32603).

so It seems it is a vscode issue - asking for a wrong line number?!

Feel free to close - I guess when this is production it will ignore errors like this instead of popping up.

Do other files in the same folder have the same name but different extensions?

Answer 2 · 2025-09-04T07:35:42.000Z

No, the filename was unique. I had moved it and then started editing.

@iisaduan I get this error every couple of minutes (in a very large monorepo).

Is there a way to silence the popup?

@richburdon That's #1867. I don't think this should be too hard to fix quick.
