“No authentication_id provided”

AI by Zapier fails on Preview with the error “No authentication_id provided”.
I am using the Standard tier with GPT-4o mini, not Bring Your Own Key.
The same error occurs on a brand-new AI by Zapier step with a simple prompt.
According to Zapier documentation, Standard uses Zapier's built-in models and should not require my own OpenAI authentication.
Could you check whether built-in AI authentication is correctly enabled for my workspace?
