harvest: renaming a directory with an invalid character does not seem to work

[atruskie]

Scenario:

A path like this /data/harvester_to_do/harvest_544/Yathong songmeter recordings potential habitat/DAW 010823 1608/DAW 01082023 `1608 was renamed to /data/harvester_to_do/harvest_544/Yathong songmeter recordings potential habitat/DAW 010823 1608/DAW 01082023 1608.

The result was we ended up with harvest items with both the old and new directories.

Questions to answer:

• why didn't the harvest items get renamed? are we monitoring the webhook? for a directory?
• the Scan job picked up the new files, but why didn't the harvest_items with paths that do not exist get cleaned up?
• does the special character make a difference in any of this?
