Hello all,
I'm trying to post bitstream policies to the REST API, and having trouble
finding what the correct format for the ResourcePolicy is. The
documentation [1] says a ResourcePolicy is
[{"id":317127,"action":"READ","epersonId":-1,"groupId":0,"resourceId":47166,"resourceType":"bitstream","rpDescription":null,"rpName":null,"rpType":"TYPE_INHERITED","startDate":null,"endDate":null}]
This looks like the policies returned by /rest/bitstreams/?expand=policies
However, when I post that policy or policies that look similar I get a 500
server error [3] on a local install of DSpace 5.
On demo.dspace.org none of the bitstreams have policies, even when I add
one in the GUI, and I get a 500 when querying
https://demo.dspace.org/rest/bitstreams/?expand=policies When posting a
policy, I get different behavior on demo.dspace.org. It gives a 400 error,
but the same exception. [2]
Can someone point me towards more detailed documentation, or provide an
explanation of what a ResourcePolicy is supposed to look like? Is there a
better or different way to set bitstream policies through the REST API or
SWORD2 API?
Thanks,

auth = ('dspacedemo+ad...@gmail.com', 'dspace')
response = requests.post(url, json=json_body, auth=auth, verify=False)
