• Copilot Chat Extension Version: v0.18.1

Steps to Reproduce:

1. Just updated VS code insiders to the version above (1.93.0-insider) and started getting the error (screenshot below). The extension is not loaded and copilot chat view no longer appears in the activity bar.
2. I have tried restarting the extension, reloading the window, restarting the application as well as switching to the pre-release version of Github Copilot (v1.220.1032 (pre-release)) but none of that worked.

Please switch to pre-release of GitHub Copilot Chat. With insiders you must use the pre-release version of copilot chat

I can probably get the message to mention this.

Updating the VS Code Insiders to the current build fixes the issue! Guess the issue can be closed now.

I started seeing this message after updating VS Studio Insiders to the latest version this morning. I am using GitHub CoPilot Chat v0.19.2024080501 (pre-release). So I suppose updating VS Studio Insiders is not an option, given I have the latest version and this causes the problem?

I uninstalled and re-installed using the specific version option. I picked one version older and it works again. Just wait to update again after a new version comes up

I started seeing this today as well in VS Code Insiders. I tried uninstalling both GitHub Copilot and GitHub Copilot Chat, then successfully installed GitHub Copilot v1.223.1064 (pre-release) but failed to install GitHub Copilot Chat v0.20.2024082301 (pre-release) with error Can't install 'Github Copilot Chat' extension. Extension is using an API proposal 'lmTools' that is not compatible with the current version of VS Code.

I'm getting the same error.

I'm seeing this as well with VSCode Insiders build.

@sandy081 It sounds like when the vscode build doesn't support the api version of the latest extension, maybe it's not finding the compatible pre-release version in the marketplace? Is that possible?

[roblourens]

@sandy081 I installed c2aa3c4625ed4b46448fa546ac5f2e93b0757718, one build before Friday's build which had an API version increase, and I can repro the issue.

I am on the following version of VS Code Insiders:

Version: 1.93.0-insider (Universal)
Commit: c2aa3c4625ed4b46448fa546ac5f2e93b0757718

Node.js: 20.15.1
V8: 12.4.254.20-electron.0
OS: Darwin arm64 23.6.0

I have the GitHub Copilot extension installed: v1.223.1065 (pre-release)

But when I try to install GitHub Copilot Chat v0.20.2024082301 (pre-release) I get the following error message:

'Can't install 'GitHub Copilot Chat' extension. Extension is using an API proposal 'lmTools' that is not compatible with the current version of VS Code.'

[roblourens]

@josephdaw You can update vscode or go back an extension version to get unstuck.

[MarvinBo]

I updated VS Code Insider to 1.93.0-insider and the GitHub Copilot extension to v1.223.1066 (pre-release). There is now error message any more, but the Copilot chat has disappeared.

[sandy081]

maybe it's not finding the compatible pre-release version in the marketplace? Is that possible?

That's true. I am not going back in versions to find the one that is api compatible. I do not remember the reason, it could be an oversight.

Fixing it.

I haven't even really initiated Insiders, but hat this too. After a few checks I saw a button to "restart extension" at the gitGub Copilot. After klicking that it was fine.

Also an issue for me once I updated to this months release:
