claude-code - 💡(How to fix) Fix [BUG] Dispatch stuck in a loop of error 400 stating content contains white-space [1 comments, 2 participants]

API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages: text content blocks must contain non-whitespace text"},"request_id":"req_011CZrP7s3mCDydNmBhXsh9G"}

TL;DR

• The issue can likely be resolved by ensuring that the text content blocks in the messages sent through the dispatch contain non-whitespace text.

Guidance

• Verify that the messages being sent do not contain only whitespace characters, as the error message suggests that this is the cause of the issue.
• Check the code that generates the messages for any potential bugs that could be causing empty or whitespace-only messages to be sent.
• Consider adding error checking to ensure that messages contain valid text before sending them through the dispatch.
• Review the documentation for the Anthropics API to see if there are any specific requirements for message formatting that may be causing the issue.

Example

• No specific code example can be provided without more information about the code being used, but a general example of how to check for non-whitespace text in a message might look like this:

if message.strip() != "":
    # Send the message
else:
    # Handle the error or add default text

Notes

• The exact cause of the issue is unclear, as the steps to reproduce the error are not well-defined, but the error message provides a strong hint about the potential cause.
• The issue may be related to a specific bug in the Claude Code or Anthropics API, but without more information, it is difficult to say for certain.

Recommendation

• Apply workaround: The best course of action appears to be adding error checking to ensure that messages contain valid text before sending them, as this will prevent the API error from occurring.
