Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.105.0. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

Yes, this broke Agent mode and somewhat Edit mode for any model.

That's a very old VS Code version

This is happening to me at 1.106.1. I got the same error as this and https://github.com/microsoft/vscode/issues/278005.

It looks like you are using a Copilot Chat version which is more than 6 months old. We made significant improvements in the meantime. We recommend that you update the Copilot Chat extension to the newest version (0.33.5). Feel free to create new issues if you still run into problems
