claude-code - 💡(How to fix) Fix Dispatch: 400 error - text content blocks must contain non-whitespace text [1 participants]

API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages: text content blocks must contain non-whitespace text"},"request_id":"req_011CZrTqSGP4NPm4tJcpi9g9"}

TL;DR

Check the conversation history for any empty or whitespace-only messages and remove them to potentially resolve the 400 API error.

Guidance

• Verify that the issue is indeed caused by a corrupted or empty assistant message in the conversation history by inspecting the messages sent in the messages array.
• Attempt to clear the conversation history again, ensuring that all messages are removed, and then try sending a new message.
• If the issue persists, try creating a new conversation or task to see if the problem is specific to the current conversation or task.
• Consider reaching out to the Claude desktop app support team for further assistance, as the issue may be related to a bug in the app.
