I've annotated a IIIF image on a project on staging, and then exported (and hosted) a derivative manifest (attached here as well).

https://recogito-staging.covecollective.org/en/annotate/8e9d7a6d-1774-4fe8-99ab-4e0168d7f918/cd3ab782-3ba4-4c7c-9f36-eec5fbe9d168?#rtab=annotations&selected=16778f77-05e8-4454-bd83-60cf51ce8e38

Adding that manifest to the public demo of Mirador works, but if I navigate to the image I annotated, and open the annotation tab in Mirador, I get an error.
