4.5 - Objectfs does not implement a trashdir.

[aspark21]

Moodle: 4.5 (dev)
objectfs: MOODLE_402_STABLE

Seems to be coming up a fair few times in the debug output on my 4.5 test site. Didn't find a Moodle Tracker relating to this but never seen this occur before so must be 4.5 specific

Objectfs does not implement a trashdir.
