SEPP fragment insertion plugin error

Thanks Nicholas!
When I try and view the full error log it says file does not exist. I tried a few different techniques to expand this error log (adding --verbose as recommended, downloading and running locally instead of on a server, adding -e in my qsub command), but I can’t get any further information besides this 2 line output:

Plugin error from fragment-insertion:
‘NoneType’ object has no attribute ‘rfind’

Is there another way to get more debug info that I’m missing?
