Prompt node in Copilot Studio requires the agent to use authentication

(1) ShareShare
ReportReport
Posted on by Microsoft Employee
I have an agent built in Copilot Studio that has authentication set to None as it will be used in a public website. The agent contains a topic where I am using a Prompt node that does not use Dataverse tables. Topic checker does not find any issues with the topic.
Publishing the agent fails, due to the Prompt node requiring authentication (which is not actually needed). The raw error message is below. This seems to be an issue with AI Builder as authentication should only be required when Dataverse tables are used. Any ideas on workarounds or if this is a known issue?

Raw error message during publish:
[
  {
    "diagnosticResult": [
      {
        "$kind": "ElementValidationError",
        "errorCode": "UserConnectionRequiresAuthentication"
      },
      {
        "$kind": "ElementValidationError",
        "errorCode": "UserConnectionRequiresAuthentication"
      }
    ],
    "componentDisplayName": "Time zones",
    "componentId": "3ea624ad-a9c4-4252-a57d-fc08daeb0ed3",
    "diagnosticErrorCount": 2
  }
]

    This error is indeed a known issue related to Copilot Studio’s Prompt nodes. Even though Dataverse tables are not involved, the Prompt node sometimes incorrectly requires authentication, especially when the agent's authentication is set to None for use in public websites.
     
    try - Temporarily set the agent’s Authentication setting to System-Assigned instead of None. This approach allows the agent to complete publishing without requiring user authentication in a public setting.
