litellm - 💡(How to fix) Fix [Bug]: Anthropic API ERROR

When I use the LiteLLM proxy relay station to request access to Anthropic models, I keep getting an error: {"error":{"message":"Invalid JSON payload: unexpected character: line 1 column 26867 (char 26866)","type":"invalid_request_error","param":"request_body","code":"400"}}

TL;DR

The error message suggests an issue with the JSON payload being sent, which may be caused by a code-level problem or an issue with the request body formatting.

Guidance

• Verify that the request body is properly formatted as JSON, checking for any unexpected characters or syntax errors, especially around character 26866.
• Review the code that constructs the request body to ensure it is correctly generating a valid JSON payload.
• Check the LiteLLM documentation for any specific requirements or restrictions on the request body format.
• Consider using a JSON validation tool or library to help identify any issues with the payload.

Example

No specific code snippet can be provided without more context, but ensuring that the request body is a valid JSON object, such as {"key": "value"}, is crucial.

Notes

The issue might be related to how the request body is constructed or encoded before being sent to the Anthropic models via the LiteLLM proxy relay station. Without more details on the code or the exact request being made, it's challenging to provide a precise fix.

Recommendation

Apply workaround: Verify and correct the JSON payload formatting to ensure it meets the expected standards, as this is the most direct approach to resolving the "Invalid JSON payload" error.
