An error occurred while submitting the agent when publish an agentic workflow on Foundry

Question

I am getting the same issue:

There was a problem submitting the agentAn error occurred while submitting the agent. Please try again.

how can I get more details

Answer 1

I think check the Foundry Activity Log at the time of the failed publish and try again with F12 → Network open to read the submit call response, and when it is still unclear, use that timestamp to open an Azure support case.

Answer 2

Use the available troubleshooting and diagnostics around publishing and dependencies to get more detail about why the agent submission fails.

1. Check for validation errors in the designer
   • In Copilot Studio / flow designer, open the agent’s workflow or agent flow.
   • Use the error-checking tools:
     • For workflows: look for red indicators on actions and open the health center banner to see all errors.
     • For agent flows: look for red indicators and select Flow checker on the top menu to list all errors.
   • You can’t publish if any errors remain, so resolve all listed issues and try publishing again.
2. Verify version history and saved state
   • Open Version history from the top menu.
   • Ensure the latest version is saved and that you’re publishing the correct version (no partially saved or outdated draft).
3. Check for missing dependencies if the agent is part of a solution
   • In Power Apps, open the solution that contains the agent.
   • Under Objects, verify that required components (workflows, environment variables, connection references) are included.
   • For any component showing Not Recognized, open the command menu (⋮) → Advanced → Add required objects.
   • Repeat Add required objects for the main Agent component, then export or republish so all dependencies are present.
4. Use troubleshooting guidance for Foundry agents and publishing
   • If the agent is being published as an Agent Application in Foundry, check the documented troubleshooting table:
     • Ensure the agent has a unique identity (agent.identity not null) if publishing to M365/Teams.
     • Confirm the required roles (Foundry Project Manager for publishing, Foundry User for invoking) are correctly assigned.
     • If tool calls or downstream access fail after publishing, verify RBAC on the new agent identity.
5. Collect diagnostics for support
   • If the error persists with no clear UI details, collect:
     • Full error details from the publish attempt (including any hidden/expanded error text).
     • Screenshots of solution layers and agent dependencies (if using solutions).
     • A description of steps already tried.
   • Then open a support case as described in the Copilot Studio support guidance.

These steps surface validation, dependency, and identity/RBAC issues that typically cause generic “problem submitting the agent” errors and give more actionable detail.
