Paella - empty video data

[Naruby Riverlione]

There must be a mistake in my workflow.

I can view the video in the engage player but via the api  (moodle plugins) I'm getting the error "empty video data"

I can view the json at the api url:
{"identifier":"829beeaa-108a-447e-a9e4-ad511983e064","creator":"Administrator","presenter":[],"created":"2022-05-26T13:17:12Z","is_part_of":"2bd89f26-b08b-4a3c-afd3-dd0580436ee7","subjects":[],"start":"2022-05-26T13:17:12Z","description":"","language":"","source":"","title":"upload 3","processing_state":"SUCCEEDED","duration":0,"license":"","archive_version":2,"contributor":[],"series":"Course_Series_2","has_previews":false,"location":"","rightsholder":"","publication_status":["engage-player","api"],"status":"EVENTS.EVENTS.STATUS.PROCESSED"}

Do I need an extra processing step ?

Something wrong the use of the engage-streaming tag ?
