Start by reproducing the purchase flow on the listed Rocket.Chat Docker setup, after connecting it to Rocket.Chat Cloud and adding a payment method. Trace the Marketplace Zoom app purchase and deployment path, including where the Unauthorized response is surfaced; no files or tests are named in the issue. Done means the purchase and deployment complete without the Unauthorized error and a regression check covers the flow.
