Hello,  
Trying to import a HAR FIle ( saved from Firefox ) , I get

Starting Recorder in headless mode

Could not convert HAR file: Error while processing HAR file

( similar in UI )

Where would I find the log? I checked in logback.xml, and no obvious setting for the HAR converter log.

Any help appreciated
