Loggers not working in Form workbench

This seems pretty basic so it’s probably a configuration that I’m missing, but I’m using FME Form v2025.1.1.0 and I have a half dozen Loggers set up to capture features that are repaired or failed in GeometryValidators that precede them.  When I run the workbench I have ‘Enable Record Counting’ set so I can see the counts going to the Loggers, but none of the messages I would expect are getting written to either the Translation Log window in FME Form nor to the log file on disk.  I’ve set the Navigator > Workspace Parameters > Log and Troubleshoot > Max Features to Log to -1 to log everything, and I’ve confirmed that the ‘Severity Level’ in each Logger is ‘Information’.  I’ve tried all 3 settings for ‘Feature Logging’ of ‘Log Only’, ‘Log and Record’ and ‘Message Only’ in various combinations of the Loggers and I’ve confirmed that the ‘Max Messages to Log’ for each Logger is larger than the number of features being routed to them. The expression in each Logger is pretty simple, e.g: Feature is: @Value(Name)

I’ve also tried configuring the log file location in Navigator > Workspace Parameters > Log and Troubleshoot > Log File and I’m getting a log file there with all non-Logger messages, but none of the Logger messages are being written.

What am I doing wrong?

Could you try replacing one of your Loggers with one with the default settings? Just to see if that logs something.

No joy, logger with default settings did not work either. Note that I kept the (non-default) workspace settings noted in the OP for my test.

Can you set that log max features back to its default? (I know you want to log everything, but let’s try this anyway)

No joy there either.  However if I pull out one of the feature classes of the half dozen that I’m reading and writing and paste it into a new workbench by itself then the logger works.

The plot thickens.  For the workbench that writes a single feature class:

  • Run with data caching enabled:  logger logs the expected Log Message
  • Turn data caching off:  logger does NOT log the Log Message
  • Turn data caching back on:  logger still does NOT log the expected Log Message.

Very inconsistent, will keep poking.

That;s really weird indeed. At this point I would suggest sending it in as a support case through your local partner, or Safe directly, and see if they can help you.
