UI Sketcher: Invalid API key, please try again

How does Cursor’s UI Sketcher work?
When I enter the API key in Set OpenAI API token in the command palette, I get “UI Sketcher: Invalid API key, please try again”,
However, the API key is not wrong and openAI charges $19.
Please let me know how to resolve this issue.

It seems that the author has stopped supporting the extension. This is not a cursor problem.

Oh my!Thank you for telling us about it.
