A new error message appears when the server fails to create an API key without explanation
What
Claude Code now has a dedicated error, KeyMintRefusedError, for when the server refuses to create an API key and doesn't give a readable reason. It shows the message: "The server did not create an API key and gave no readable reason. If this keeps happening, contact support."
Why
This gives a clearer, more specific message when API key creation silently fails, and points you toward contacting support if the problem persists instead of leaving you with an unexplained failure.
