openai-python: None is not of type ‘object’

I think the issue is related with “function_call” being null (or None in this case), I have removed it from incoming message of openai and the problem is gone.

problem stopped after I did @aemr3 's advice, thank you

You likely need to pass exclude_unset=True when converting the model into a dictionary.

@ganlbarone

{‘timeDisplay’: {‘type’: ‘string’, ‘description’: ‘Time must be displayed in a time stamp format YYYY-MM-DD 00:00:00 at midnight.’}}, ‘type’: ‘object’, ‘required’: [‘timeDisplay’]}}] is not of type ‘object’ - ‘too ls.0.function’",

Just a guess without knowing the tool api: there you say timeDisplay is 'type': 'string' and then the error says 'timeDisplay' is not type 'object'. But I don’t know really.

Maybe using the python client would be easier to get those things right.

I actually ended up figuring out the problem. The function node in the json cant be an array. That was the part that was breaking it. Tools is an array, that can contain multiple funtions, but function itself is singular.

It isnt working exactly how I want/expected it to from a feature standpoint, but that is a me problem to sort out now that the JSON is structured appropriately and the API isnt erroring.

Anyway, just posting this back in case anyone runs into this type of error, their return errors could likely be a bit more robust than they are.

I have the same issue with openai 1.2.3. Error message is:

Error code: 400 - {'error': {'message': "None is not of type 'object' - 'messages.2.function_call'", 'type': 'invalid_request_error', 'param': None, 'code': None}}

Message logs are like this:

[{"role":"system","content":"You are  [REDACTED]"},{"role":"user","content":"[REDACTED]"},{"content":null,"function_call":null,"role":"assistant","tool_calls":[{"index":0,"id":"[REDACTED]","function":{"arguments":"{\"query\": \"[REDACTED]\"}","name":"[REDACTED]"},"type":"function"},{"index":1,"id":"[REDACTED]","function":{"arguments":"{}","name":"[REDACTED]"},"type":"function"},{"index":2,"id":"[REDACTED]","function":{"arguments":"{}","name":"[REDACTED]"},"type":"function"}]},{"tool_call_id":"[REDACTED]","role":"tool","name":"[REDACTED]","content":"[REDACTED]"},{"tool_call_id":"[REDACTED]","role":"tool","name":"[REDACTED]","content":"[REDACTED]"},{"tool_call_id":"[REDACTED]","role":"tool","name":"[REDACTED]","content":"[REDACTED]"}]

Sorry, I had to redact confidential information.
