'Keep Chat edits in this file' button is frozen for Co-Pilot

[jeffaxup]

Type: Bug

After applying a new code changes recommended by Co-Pilot in the code editor, there is a Keep/Undo popup which appears. You can't save and use the changes without clicking 'Keep' apparently (slightly confusing since really you only know if you want to Undo it until after you've saved the file and ran it). In any case the 'keep' button appears active, but clicking on it does nothing. It should save and disappear as it normally does. I have had this happen multiple times in the last few days and I have to restart VSC to clear it. Bug.

The "freezing/unresponsiveness" of the Keep/Undo 'Apply in Editor' dialog seems to be in cases where no changes are actually made. There is no red or green highlighting in the code. For some reasons it suggests changes, but then can't make them. In these cases it should be generating an error message, or asking to redirect changes to a different file. Instead it freezes the popup and neither keep or undo works and I have to reset the IDE.

Can you please check the dev tools console for errors pointing towards this? Do F1 > Toggle Developer Tools > Console

This was several days ago and I'm not even sure if the errors are relevant to this topic. I can keep an eye on this and see if anything turns up after this happens next. here are some of the recent ones:

• console.ts:137 [Extension Host] TypeError: fetch failed at node:internal/deps/undici/undici:13502:13 at processTicksAndRejections (node:internal/process/task_queues:95:5) at qP._fetch (
• ERR [Extension Host] TypeError: fetch failed at node:internal/deps/undici/undici:13502:13 at processTicksAndRejections (node:internal/process/task_queues:95:5) at qP._fetch (
• Extension Host] Failed to fetch remote embeddings cache from https://embeddings.vscode-cdn.net/text-3-small/v1.100/settings/ms-python.vscode-pylance.json

This has happened a number of times now. This seems to be the scenario:

1. Copilot (in chat mode) suggests a code change.
2. I click the button to apply it to the file
3. Behind the scenes it uses some kind of "implementation mapping" to know which file to put it in and where to make the change.
4. Typically it makes the change, shows the new code in green, and I click the 'Keep' button and then the popup layer disappears.
5. In this case, there is no green or red. So I think it was unable to understand the "implementation mapping" and did not make any code changes. In some cases it was the wrong file to apply it to, but in other cases it just can't find the location in the file to make the update.
6. So instead of giving an error and saying "unsure of how to apply this change", it just freezes that popup.

I've seen this happen maybe 10 times now in various similar scenarios. I have discovered that if I just ignore it and go to another file, I can ask Copilot to review that change and again and give me the code to apply again. Sometime it works after it does it a second time, or after I direct it towards the correct file to modify.

So I would say that this is a both a UX problem and a technical problem of getting "implementation mapping" to be accurate, and also give proper errors and recovery paths.

OK here is the console logs in VSC: Some of the earlier errors may have been due to the server being down earlier, but I'm including them for context. Somehow Co-pilot is unable to process the recommended changes and does not implement them in the target file. It then doesn't know how to proceed and freezes the dialog.

This actually happens quite often. Currently I'm using 'Ask' mode with GTP-4o. I ask it to check the code and suggest changes, and then when I go to apply the changes it makes no modifications to the file. Then it freezes the Keep dialog.

Problems are paused because: "Chat Edits", using Python.

After trying to implement ASCII art using the co-pilot tool as well.

The entire IDE hangs and it's difficult to exit the AI integration cycle or whatever it's doing.

Sometimes the operation is interrupted with the following popup error:
