HI, I am trying to change the openassessment module to use filesystem
storage instead of s3. But on the CMS insterface when I try to create a
peer to peer exercise and I chose the option that is obligatory to upload a
file i receive the next error:

On the CMS a loading red circle appears to show that there is an error but
the exercise seems to work fine without errors, only in the log.
Can someone help me to solve this error?
