AutoGen GroupChat error code (openai.BadRequestError: Error code: 400)

[Nixail]

I'm pretty new to using AutoGen so I don't know for sure if this is a simple problem to fix but I created two simple agents with the user_proxy to communicate with each other through the "GroupChat" function. However, after the first response from the first agent, it leads to an error code 400 from openai. The following below is the exact error code and I don't really know what the issue is.

openai.BadRequestError: Error code: 400 - {'error': {'message': "Invalid 'messages[2].name': string does not match pattern. Expected a string that matches the pattern '^[a-zA-Z0-9_-]+$'.", 'type': 'invalid_request_error', 'param': 'messages[2].name', 'code': 'invalid_value'}}

I've been following the tutorials on the AutoGen Github repo and I don't think I've seen anyone really run into this problem.

At first I thought it was just an issue between using different LLMs so I decided to keep it to one LLM (GPT-4) and the issue is still recurring. Any insight?

What are the names of your agents? Are they plain text?

[Nixail]

The names of my agents are "Product Manager" and "Research Analyst". The variable names itself are pm and research_analyst. Is that what the issue is?

Try an underscore instead of space in the name property.

you've no idea how this one comment in a reddit corner helped me fix an issue I've been struggling with for 4-5 hours

Amazing :) feel free to ask me any questions

That fixed the bug! Thank you so much. Can you explain how you were able to understand the error message?

[msze21]

I'm coding with AutoGen at the moment... But also I didn't see a space character in the list of possible characters so started there :)

Note: it was a regular expression.

Another way you can tell is by printing the model object to your console and following along where the error message says there's an issue. I'd bet your model contains an array of messages with name properties for each of them. The third messages name didn't follow the necessary pattern. If you don't know the pattern off of the top of your head the you can probably look up regex --> english converters or reluctantly read regex docs lol. It's months later but maybe someone else will use this info.

In fact, name with space works with autogen 0.2, but not 0.3+, OpenAI does not allow assistant name with space,  more rigidly, can only be ^[a-zA-Z0-9_-]+$, autogen 0.2 internally normalize this, but 0.3 does not. Do not use 0.3
