"Incompatible Model Error" or "JSON Error"

[sackosindou]

Hello, I'm encountering an issue with installing and running the GPT Researcher application. After following the installation steps, the application returns several errors when I try to initiate a search.

Steps Followed to Install the Application:

Empty results after research on the application :

Summary of the Errors Encountered:

Incompatible Model Error: I receive a message indicating that my API key does not have access to the gpt-4o-2024-08-06 model. It seems that the required model is not activated for my account, even though I have an active subscription on https://chatgpt.com/.

JSON Format Error: The message "Error in reading JSON, attempting to repair JSON" appears, suggesting an issue with the JSON configuration file. It seems the application is unable to read or load the default.json file correctly.

NoneType Error in JSON Parsing: A TypeError: expected string or bytes-like object, got 'NoneType' error occurs, indicating that the expected response is empty. This could be related to a missing API response or error handling issue in the code.

Here is the code with errors :

@sackosindou it seems like your OpenAI account does not have permissions to the proposed model or is not configured well. Did you export the OpenAI api key? Also try changing the model to gpt-4o

[sackosindou]

1 - Export of the OpenAI API Key

I had already exported the OpenAI API key in the .env file.

Location of file .env :

Content of file .env :

2 - Changing in model to gpt-4o

I have just updated Model here :

3 - Code errors after model changed

Welcome @sackosindou

Looks like the meaningful part of the error message:

Error code: 403 - {'error': {'message': 'Project proj_2VxSRsTQaqjx5PDs2D0LEpindoes not have access to modelgpt-4o`', 'type': 'invalid_request_error', 'param': None, 'code': 'model_not_found'}}

It looks like you'll want to test your LLM independently with this script

If you don't have access to gpt-4o, you can try one of these other configurations

[sackosindou]

Thank you for your help! I was able to resolve the issue by adjusting to the correct model. I appreciate your support. Closing the topic now.
