Hi, We have created a workspace in FME Desktop 2019.2. We recently upgraded our install of FME Desktop from 2019.2 to 2021.1 and now the AttributeFilter block isn't working anymore. It was working perfectly in 2019.2. What am I doing wrong?

By default Workspace will not upgrade transformers, you'll have to do that manually (check the "Upgradeable Transformers" list in your Navigator). However, it should work without upgrading.

A few questions to try and see if we can get to the bottom of this:

• One of the ports on your AttributeFilter is not connected, is this by design or was it connected in 2019?
• Are you sure there's actually data going into it?
• Can you show and/or tell us a bit more about the workspace?
