Description

Trying to copy a test project from pirca to tordo.

First, the project contained only collections and container requests. The collections were copied, container requests ignored (as expected).

# on shell.tordo
$ arv-copy pirca-j7d0g-bbu5p6jsjjfokta

Then, I copied a registered workflow into the project, and tried to copy it again:

$ arv-copy pirca-j7d0g-bbu5p6jsjjfokta

During handling of the above exception, another exception occurred:

Interestingly, this doesn't seem to happen all the time:

That's really weird. Seems like some kind of ruamel.yaml failure. Bad version maybe?

17962-check-wf-definition @ 972272c42f7ad8daaef29d3d981968e566f3f087

developer-run-tests: #2806

The reason this failed was because the specific workflow record in the bug report had null in the "definition" fiend. I don't know how that happened, but arv-copy didn't like it.

I've improved the error handling for arv-copy a little bit.

Actually it was on purpose, it makes it usable in a script (you can capture stdout to get the uuid of the copy). Although it's technically out of scope of the ticket so I can pull it out if you think I should.

I think it's a good idea but also guess that it should be validated with a test and maybe some documentation (ie: on the command's --help message)
