Cannot read properties of undefined (reading 'getModelColumnOfViewPosition')

[RedCMD]

2nd time I got the error Cannot read properties of undefined (reading 'getModelColumnOfViewPosition')

has only happened twice
both times it was when I ctrl+A ctrl+X all the code in a .tmLanguage.json file

Windows 11 x64 zip installation
VSCode 1.8.4 stable

Does this reproduce in the latest VS Code insiders build with all extensions disabled?

If it does, please share the file which causes this

I just experienced this while doing a first test with Github Copilot inline chat refactorisation

1. I selected a all lines in a typescript file (~19 LOC)
2. I started an inline chat and asked it to refactor it to use proper functions instead of consts
3. It started streaming correctly, but then got that error message (Cannot read properties of undefined (reading 'getModelColumnOfViewPosition')

This was repetable.

Interestingly, when I only selected the first 10 LOC it worked as expected.

Please share the TS code and copilot prompt you used

I have experienced the same error under the same circumstances as mjbvz

I recently ran into the same issue when asking Copilot to write a simple ETL script using TS and Node 20. Didn't resolve even when I disabled all other extensions. There's nothing in logs other than successful [fetchCompletions] requests

Prompt

Make this code take every file inside ../api/schemas/ (including nested files) and compile it using compileFromFile() and then write the result to a corresponding file in ../api/types overwriting if needed

I too got the same error for Github Co-pilot. It stopped generating the response with the below error

If i modify this prompt to "Convert to module" it generated the response.

FYI

[RoyPrinsGH]

Same issue here. Only happens when I select all lines in a file and use CTRL + I to request an edit.

[coffee-mug]

Same issue here. What's strange is that the prompt worked fine for another file, that uses the same structure overall. Cannot share the prompt publicly as it uses some information from a database.

If this happens to anyone just restart the application it solves it everytime it appears for me
