Error Message

unhandlederror-Cannot read properties of null (reading 'name')

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.

Cannot read properties of null (reading 'name') on an upload/drop code path (sample stack had REDACTED user file paths). No prior tracking issue found.

⚠️ Server-side deminification returned no-frames-mapped; the stack in the issue body may be minified. Manual investigation recommended.
