type_error
Invalid input: Expected an object type but received None instead.
This error has been identified and solved.
Reason
The 400 status error in the OpenAI API, specifically the error message None is not of type "object" - "messages.2", indicates that the server could not understand the request due to invalid syntax or configuration. Here are some possible reasons for this error:
Invalid Request Structure
The error suggests that the messages parameter in your request is not formatted correctly. Specifically, messages.2 is expected to be an object, but it is receiving a None value, which is not valid.
Incorrect Data Types
The API expects specific data types for each parameter, and if these types are not met, it can result in a 400 error. In this case, the error indicates that a required object is missing or is of the wrong type.
API Request Validation
The OpenAI API has strict validation rules for the requests it receives. If any part of the request does not conform to these rules, such as missing or incorrectly formatted fields, the API will return a 400 error.
Solution
To fix the 400 status error in the OpenAI API due to an invalid input, you need to ensure the following:
Validate the request structure: Ensure that all required fields, especially the
messagesparameter, are correctly formatted as objects and do not containNonevalues.Check data types: Verify that all parameters are of the expected data types, particularly that the
contentfield of each message is a non-null string.Strip unnecessary characters: Make sure to strip new lines from the beginning and end of any text inputs.
Review API key and environment variables: Ensure there are no hidden characters or encoding issues with your API key or environment variables.
Comply with API documentation: Refer to the OpenAI API reference to ensure all parameters, such as model specifications and dimensions, are correctly specified and supported by the model you are using.
