metadata field not saving

[saracarl]

There's a drop down for author here:

https://fromthepage.com/stefansson-wrangel-09-01-001-5b5d7392-6e7c-4ae5-a675-e3f82fdeb60a/wrangel-island-set/stefansson-wrangel-09-01-001-5b5d7392-6e7c-4ae5-a675-e3f82fdeb60a/save_description

But if you choose an author it isn't saving. I'm not seeing any errors or warnings in the logs, on this:

What I'm noticing is that we're passing the work_id as the user_slug; perhaps that is the problem? "user_slug"=>"stefansson-wrangel-09-01-001-5b5d7392-6e7c-4ae5-a675-e3f82fdeb60a "
