In ma-core 2.8.8 I could not get the Generate History function to work on my script when there were debug logging function calls in the script.
generateMetaPointHistory causes ERROR on LOG.debug() even if log level is "None" in metadata script. No error messages were shown on the web interface. The history generation simply did not work. It was puzzling because the function worked, and other metadata history generation worked. Once I remembered to check ma.log, I found the problem:

As a work around, I had to comment out all LOG.debug() calls from my script.
