hi, 
 
when trying to download the manifest zip file (test and published) in copilot studio, I get the following error :
{
    "ErrorCode": 500,
    "ErrorMessage": "Value cannot be null. (Parameter 'name')",
    "DiagnosticsMessage": null,
    "ErrorInfo": null
}
 
Somebody has an idea of the cause?

    In Copilot Studio, double-check the App ID, App Name, and other relevant fields to make sure they are not empty or have incorrect values.
     
    Ensure that the App ID, Client Secret, and other Azure AD-related configurations are properly set up and linked to the bot in Copilot Studio. A mismatch or missing value in Azure AD configuration can sometimes lead to this error during manifest generation.
     
    If you have any custom properties in the manifest or have added new capabilities, ensure that their names and values are correctly defined. An incorrect or null value in these properties could be triggering the error.
     
    Thanks.
