Keep on getting KeyError: 'response'

[hamaryns]

Hi, recently, I keep getting KeyError: 'response'. When I restart, it resumes the previous import, but the files that were recognised last time are still there and I have to confirm them again. But then a bit later it crashes. See log.
beet.log
Can I somehow reset beets’ metadata so that it does not do this every time?
