"decoding Unicode is not supported" when uploading secret using unified CLI

[Stephen Balukoff]

When using the unified OpenStack CLI, we get a "decoding Unicode is not supported" error when creating a secret. Like so:

openstack secret store --name='test-secret' --payload-content-type='text/plain' --payload='blahblahblah'

Further, we don't get output that shows us the details of the secret that was (successfully) created.

Note that this doesn't happen (though there are plenty of other warnings) when using the deprecated barbican CLI:

barbican secret store --name='test-secret2' --payload-content-type='text/plain' --payload='blahblahblah'

This is a bug of barbicanclient, and should be fixed with this commit https://review.openstack.org/#/c/386938/

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/python-barbicanclient 4.2.0 release.
