Error When Running the Program

When trying to run the program using the following command:

$ python3 main.py

I received the following message:

[Pythagora] What is the project name?
> UIchatGPT
[Spec Writer] Describe your app in as much detail as possible
  [example]: Start an example project
  [import]: Import an existing project
 
#### **Integration with Third-Party Services:**
1. **OpenAI API:** The program integrates with the OpenAI API to call the artificial intelligence model and send/receive data.
2. **Authentication Using API Key:** The program requires setting the user's API key to access OpenAI services.
 
### Summary
This program is a simple yet effective application for chatting with ChatGPT, providing users with an easy and quick way to interact with the artificial intelligence model through an interactive interface.

MissingGreenlet: greenlet_spawn has not been called; can't call await_only() here. Was IO attempted in an unexpected place? (Background on this error at: https://sqlalche.me/e/20/xd2s)

Error Details

It seems that the MissingGreenlet error indicates that there is an attempt to call an asynchronous function (await_only()) in an unexpected place, which may result from not calling greenlet_spawn in the correct context.

Note: I was working on the program through the command line only.

Request for Help

Can you help me identify the cause of this error and how to fix it? Thank you in advance for any assistance!

I fixed this by modifying core/db/models/specification.py and changed line 37 from:

 complexity: Mapped[str] = mapped_column(server_default=Complexity.HARD)

to:

 complexity: Mapped[str] = mapped_column(default=Complexity.HARD)

And also changed line 55 to:

complexity=self.complexity if self.complexity else Complexity.HARD,
