    To perform this test, I created a Copilot agent with multiple PDF files containing service pricing information.
    The agent in question works well and ultimately provides me with a coherent quote after some questions / answers.

    I wanted to see if it was possible to directly submit a PDF file containing the customer's request, but it does not work.
    So I added a Request-type tool with a GPT prompt.
    This tool works in test mode: I upload a PDF file, it understands its content and gives me a clearer text describing the requirement.
    But it doesn't work in the Copilot agent.

    I wonder if I should use a PowerAutomate flow rather than this Request-type tool directly.

    Hello,

    I'm back with my problem.
     
    To debug i create a powerautomate flow wich call my API endpoint and it's working (detection of newfile in Sharepoint, send to api, response in JSON).

    Why is it not possible to do the same thing easily with Copilot?

    I read theses docs : 

    https://learn.microsoft.com/fr-fr/microsoft-copilot-studio/image-input-analysis
    https://learn.microsoft.com/fr-fr/microsoft-copilot-studio/guidance/pass-files-to-connectors

    I discovered that in the meantime it was not possible to transfer files in test mode.

    Please help, it's so frustrating...
