Fix ParamValidationError
in AutoGPT
✅ Solution
ParamValidationError in AutoGPT often indicates an issue with the format or validity of the input parameters being sent to an API or function, such as the URL in ExtractWebsiteContentBlock. To fix it, carefully validate your input parameters against the expected schema or requirements of the receiving API or function *before* sending the request, paying close attention to data types, allowed values, and required fields, and implement specific error handling around the parameter validation. You can use tools like pydantic to enforce these data constraints directly in your code.
