    I encountered an error doing what you asked. Could you try again?

    Try what?

    I already tried another example and It doesn't work! I don't know why!

    Hi Ahmed,

    What environment type are you using? A CHE where a Power Platform environment is linked, a Tier2 sandbox or an UDE environment?
    After building the code, have you also performed a full database synchronization? That task should register the plugins for Copilot Studio.

    A 400 error can also mean that returned data from the X++ plugin is too large. See also: Troubleshoot connector request failure - Microsoft Copilot Studio | Microsoft Learn

    It's a sandbox environment linked to my UAT and yes power platform is linked.. exactly like the tutorial.
     
    Data can't be large since the tutorial returns only 3 variables (balance, currency and boolean)
