[{"error":"Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":"req_011Cb6hDrxqXuHmAE46XGoXH"}\n at generate (/$bunfs/root/src/entrypoints/cli.js:11:62549)\n at makeRequest (/$bunfs/root/src/entrypoints/cli.js:51:7694)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-05-16T18:08:05.142Z"}]

TL;DR

The issue is likely due to a server-side error, and the user should try to reproduce the issue or wait for the server to recover.

Guidance

• The error messages indicate an "Internal server error" with a 500 status code, suggesting a problem on the server-side.
• The repeated errors with the same status code across different timestamps imply a persistent server issue.
• The user can try to verify if the issue persists by retrying the request after some time or checking the server status.
• If the issue is intermittent, the user may want to capture more detailed logs or error messages to help diagnose the problem.

Notes

The provided information does not give clear insight into the root cause of the server-side error, so it's difficult to provide a specific fix.

Recommendation

Apply workaround: Wait for the server to recover or retry the request after some time, as the issue seems to be server-side and not related to the client configuration or code.
