We were seeing this error in the deployed tests:

I could not reproduce this issue. Couldn't figure out how to get these messages. Also text search on OC sources could not fine the error message.

grep -Rn '.' -e 't be sent to'

notification remote_share#10 can't be sent to Demo Test (SRAM CO) via email: the user is missing

This sounds like an email is sent to a user when they receive an incoming share via OCM. This process apparently assumes that shareWith is a user. But now it's a group, so that's why the email can't be sent. We could just ignore this error, but it would be nice to find a way to stop it from trying to find an email address for the group each time an OCM-to-group share comes in! :)

Moving this issue to the OCM app.
