Hi!
This is an error at the plugin (I’ve fixed it here: Missing mapping for the "inProgress" state · Issue #18 · pkp/pln · GitHub, but we didn’t release a new version of the plugin with the fix yet), basically it doesn’t recognize the status sent by the preservation network (inProgress) and considers something went wrong.
I can confirm the deposit has been received, and will probably be preserved in a couple of days (once all the involved organizations grab a copy of it).
Best,
Jonas
