[ianballou]

What are the changes introduced in this pull request?

Adds another error to catch that was found to have been raised on another machine when debug logging the push body.

Considerations taken when implementing this change?

What are the testing steps for this pull request?

Try pushing container content to Katello. To enable this, add

  :container_image_registry:
    :allow_push: true

to Katello's config file and ensure that your pulp-container has pulp/pulp_container#1589.

podman push 66640e9653de hostname/organization/product/arianna

I cannot reproduce this on another machine, so here's the old stack trace to go off of:

I did add this same fix to the reproducer machine and pushing worked right after.
