[Error] [GitHub.copilot-chat] unhandlederror-Invalid string length

## Error Message
````
unhandlederror-Invalid string length
````

## Stack Trace
> ⚠️ **Stack not deminified** — no frames could be mapped to original source. The frames below are minified; line/column numbers refer to the bundled JavaScript, not the original TypeScript source. To deminify, either re-run the `create_issue` MCP tool with the VS Code build commit hash (and, for extension errors, the extension id + version), or call the standalone `deminify_stack` MCP tool.
