Build pod doesn't start because of invalid pod name

[jmjamison]

I hope I am putting this in the correct place.

Bug description

I've tried using a jupyter notebook that is in a dataverse repository.

Expected behaviour

I thought the jupyter notebook would open in mybinder web interface

Actual behaviour

Seems stuck at "waiting to start"

How to reproduce

1. Go to mybinder
2. Copy the dataverse doi
3. Click on launch button
4. See error

Your personal set up

• Version: Using mybinder.org - doesn't have version information

Hey @jmjamison, I tried with a DOI from Harvard Dataverse (10.7910/DVN/WIAEL2) and it worked as expected. What's the DOI that you're trying to use from UCLA's Dataverse?

[jmjamison]

This from UCLA's Dataverse: 10.25346/S6/DE95RT

Thanks for reporting this @jmjamison - it seems like this particular DOI doesn't work :-/

For me https://mybinder.org/v2/dataverse/10.25346/S6/DE95RT/ shows "waiting for build to start". Looking into the server logs I see the following:

The problem is that the name ends in a -. Not quite sure why this happens, so we will have to investigate. Unfortunately there is nothing you can do to work around this :(

I tried the same doi and still stick at waiting to build.
