2. Mount
3. Wait until the docker container's logs stop "scrolling" and you'll be able to see the error message

Need to investigate/reproduce.

[korydraughn]

The exception indicates Jargon could not find /tempZone/trash. Perhaps this was caused by a bad configuration, missing trash collection, or invalid arguments to the mount command.

In any case, the application did its job by reporting an error.

I don't think there's anything actionable here.

That sounds fine. Closing as resolved/invalid.
