lulu10922 Can you set "C_Cpp.copilotHover": "disabled" as a workaround?

lulu10922

VS Code Version: 1.87.2 is from Feburary 2024 -- the Copilot hover might require a newer version (1.90.0 or newer).

lulu10922 Can you upgrade your VS Code version?

lulu10922

lulu10922 Do you have the GitHub Copilot (Chat) Extensions installed? If so, what versions?

The API was added in VS Code version 1.90.0 in commit microsoft/vscode@6990923 (it got renamed).

Our code only checks that the lm exists and not the particular function.

        // Ensure the user has access to Copilot.
        const vscodelm = (vscode as any).lm;
        if (vscodelm) {
            const [model] = await vscodelm.selectChatModels(modelSelector);

In 1.87 of VS Code, that API was in a "proposed state" and was subject to breaking changes until it got out of the proposed state.

I'm not sure if there's a recommended fix on our part.

We only added the selectChatModels call in December 2024 in PR #12552 .

Merge main to vs (#13828)

lulu10922 Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.27.0 (assuming you didn't fix it by upgrading VS Code).
