I am getting error M3003 when running "Discussion Summary" on GitLab Ultimate trial and duo Enterprise trial

Problem to solve

I am trying GitLab Ultimate with Duo Enterprise and this is only my 3rd day. Why is it that I am getting M3003 from the Duo Chat when I click on the “Discussion summary” button from one of the issues that I created and that has many comments from 3 GitLab accounts?

Steps to reproduce

I tried to run the “/summarize_comments” from the Duo Chat itself and I keep getting the same error.

Configuration

I am using GitLab.com SaaS with GitLab Ultimate and Duo Enterprise trial
