error when connecting credential with Open AI

I’m currently on the 14-day n8n Cloud trial and working through one of the suggested beginner sample workflows. I’m encountering the following error in the “OpenAI Chat Model” node:

You don’t have access to the credentials in the ‘OpenAI Chat Model’ node. Ask the owner to share them with you.

Here’s what I’ve tried:

  • Deleted all credentials and the node.
  • Recreated the node and a new OpenAI credential (which tests successfully).
  • Selected my new credential in the node.
  • Still receive the same error and cannot save my workflow.

I am the only user in my workspace.

Could you please help me resolve this so I can continue with the sample workflow?

Thank you,
Mike
