Fix It (try in order)

1. Update the extension (most likely fix)
   The error was reported 2 hours after a release — a patch is probably already out.

VS Code → Extensions → GitHub Copilot Chat → Update

2. Reload VS Code

Ctrl+Shift+P → type "Reload Window" → Enter

3. Clear extension cache
   Close VS Code, then delete this folder:
   C:\Users\alberto.sanchez.INFOBRAS.vscode\extensions\github.copilot-chat-0.38.1
   Reopen VS Code — it will reinstall the extension automatically.
4. Roll back to previous version (if update breaks things)

Extensions → Copilot Chat → ⚙️ gear icon → Install Another Version → pick the one before 0.38.1

Bottom Line
Bad release of v0.38.1. Updating or reloading should fix it. If not, roll back.

[iamamits]

This error usually happens when the Copilot Chat extension receives an unexpected value (not an array) while trying to update UI items.

The stack trace shows the problem in:

github.copilot-chat/dist/extension.js → setItems()

This typically happens due to one of the following reasons:

1. Extension update cache conflict
2. Corrupted extension installation
3. VS Code API change not fully supported by the extension version

Possible fixes you can try:

1. Reload VS Code Window

Run the command:

Developer: Reload Window
use Command : CTRL + SHIFT + P and search for reload window

2. Clear Extension Cache

Close VS Code and remove the Copilot Chat cache folder:

C:\Users.vscode\extensions\github.copilot-chat-0.38.1

Then reinstall the extension from the marketplace.

3. Reinstall Copilot Extensions

Remove both extensions and reinstall them:

• GitHub Copilot
• GitHub Copilot Chat

4. Check for Updates

Since this release was updated recently, it might be a temporary regression. Updating to the next patch version usually fixes these runtime errors.

5. Disable conflicting extensions

Sometimes other AI or chat extensions interfere with Copilot UI components.

Try starting VS Code with:

code --disable-extensions

Then enable only Copilot extensions.

If the issue persists, it would help to attach the Developer Tools console logs:

Help → Toggle Developer Tools → Console

This may reveal which value is being passed as e that is not iterable.
