claude-code - 💡(How to fix) Fix [BUG] Dispatch API Error: 400 [1 participants]

API Error: 400 {“type”:“error”,“error”:{“type”:“invalid_request_error”,“message”:“The request body is not valid JSON: invalid high surrogate in string: line 1 column 295204 (char 295203)”},“request_id”:“req_011CahoftjanfvWauQNnAfto”}

TL;DR

The issue is likely due to invalid JSON in the request body, causing a 400 error, and can be fixed by ensuring the request body is valid JSON.

Guidance

• Verify that the request body being sent to the API is valid JSON, checking for any special characters or encoding issues that may be causing the "invalid high surrogate in string" error.
• Review the code that constructs the request body to ensure it is properly encoding any special characters or non-ASCII text.
• Check the API documentation to see if there are any specific requirements for request body formatting or encoding.
• Test the request with a simplified payload to isolate the issue and identify the specific character or string causing the error.

Example

No code example is provided as the issue does not include specific code snippets, but the error message suggests focusing on JSON encoding and special character handling.

Notes

The issue may be related to the specific Claude model or version being used, but without more information, it's difficult to determine the root cause. The error message suggests a JSON encoding issue, which should be the primary focus for debugging.

Recommendation

Apply workaround: Ensure the request body is valid JSON and properly encoded to fix the 400 error, as the root cause appears to be related to JSON formatting rather than a version-specific issue.
