I have a topic which accepting files as input and passing it to GTP4 model. But looks like topic is not accepting file as input. I am using 'Test your agent facility' to upload files but file is not getting passed to GTP4 model.
 
Here is the error 
Error Message: The prompt 'JDvsCV' ('fbb14c8e-1a7b-49f0-9a78-7ea62e5c3cfc') failed to run with response code '400'. Error Code: AIModelActionBadRequest Conversation Id: 7c6af0e9-b8f1-4bd2-9b5c-03da127bb213 Time (UTC): 2024-12-18T16:35:56.179Z

    Confirm whether the GPT-4 model being invoked supports file input directly. GPT models generally expect text input only.
     
    As per my understanding, file upload is not possible.

    Since direct file handling is not supported, we need to use Power Automate or Azure Functions to handle file uploads.

    Later Extract file content and send the extracted text to the GPT-4 model through the Copilot Studio topic.

     
    Thanks.

    GPT 4 is multi module , it accept file as input and. I have tested the model and its working fine. Main issue is passing file from Copilot to model.
