qianfan.errors.APIError: api return error, req_id: as-3euhp023ev code: 336003, msg: function_call's name can't be blank

[Puiching-Memory]

Hey, guys. When I run the following code there is an error, I am not clear what I did wrong.
I am building langgraph using GPT provided by the Qianfan platform. In this figure, I will directly judge the output of GPT, if it is not successful, I hope it can be regenerated.
The judgment function is written on another server, which will run the GPT generated code and return an error report, or a success.

I think there was an error going back to the GPT rebuild step.
