The request that is failing is configured to follow a link from a previous request. You said that you have the issue while running a test and not from a validation. How many users have you run in your test?

This error is a consequence and not the root cause. You need to check the content of the previous response it's probably different than expected. For example it can happen when a login fails.

You can run your test in debug mode to ease the troubleshooting.
