Fix BadRequestError

in Anthropic SDK

Solution

BadRequestError in the anthropic-sdk usually arises from sending malformed requests to the Claude API, such as including unexpected or incorrectly formatted data fields like extra headers. To resolve this, carefully inspect your request payload, especially custom headers, output format specifications, and any extra fields, ensuring they strictly adhere to the API's requirements and documented schema; remove any extraneous or incorrect elements that are not explicitly supported.
