I’m trying to set up an automation with a merge process similar to what is described here
Getting Started with the Split-Merge Block – FME Support Center
However, when I try to add in a Merge action to the Failure port I get the following error message

Has anyone encountered this? I’m using the Merge Tool with a Failure Port so I’m not sure why it’s complaining
