Hello everyone,

I can't seem to find anything about this so decided to post a question here. We've been having issues with some of our automations ever since we upgraded from FME 2020 to FME 2022. These workflows use SchemaMapper to configure and export shapefiles based on a clipped location, and what we've been seeing is that the SchemaMapper will fail (the logs say something like "A required column was not found, row fme_feature_type will be skipped") and a bunch of the shapefiles that should have been clipped and saved in the output folders are missing.

I noticed that, even though the Schema Mapper is able to read the Excel spreadsheet we're using (ie. everything shows up properly in the "Parameters" section), once you hit the 'Next' button the Preview appears empty. That is, all the tables show up in the pull-down menu but the view pane itself appears empty (see screenshot 1). And this is what shows up in the Create Attribute Map window (screenshot 2)

As you can see, it says it can't read the source and destination attribute fields even though it shows the proper selected table right below. Hitting the refresh button doesn't do anything.

It's like the 2022 transformer is having trouble retrieving the information from the table past the reader stage. So, when the workbench is run and it fails because SchemaMapper can't find a required column it's because it can't retrieve anything.

On the other hand, everything works (and shows) properly in 2020, even reading from the same exact files.

Has anyone encountered this issue?
