Issue/Introduction

After upgrading Tanzu RabbitMQ on Tanzu Platform to version 10.4.1, the On Demand Instance Smoke Tests may fail.

The smoke test passed for some plans, but after about one hour it failed with the error message: "Credentials were rejected, please try again".

Here is an example failure log:

Environment

Tanzu RabbitMQ on Tanzu Platform 10.4.1

Cause

The new smoke test logic was introduced starting with version 10.4.1.

Initially, the cf user tile_installer can authenticate successfully and create the service instance and service key. However, the UAA access token expires after one hour, which leads to failures.

A re‑login scenario will be implemented to address this issue and prevent the error.

Resolution

Workaround: Skip the On Demand Instance Smoke Tests errand during tile installation or upgrade, or run the smoke test with fewer plans.

This issue will be fixed and delivered in future releases of Tanzu RabbitMQ on the Tanzu Platform. The KB will be updated accordingly if a fixed version is released.
