Hi Ludovic
The URL query parameter should be asOfDateTime, not asOfVersionDate.
It looks like the HTML response to /objects/{pid}/datastreams/{dsid}/history
is incorrect in that the URL it provides for the content link incorrectly
uses asOfVersionDate.
This is a bug, I have raised https://jira.duraspace.org/browse/FCREPO-812
for this.
If you modify your URLs to use asOfDateTime instead of asOfVersionDate, they
should work correctly.
Pending resolution of this bug, you can fix this issue locally by editing
the file $FEDORA_HOME/server/management/viewDatastreamHistory.xslt: search
for asOfVersionDate in this file and replace it with asOfDateTime, and the
"history" URL should then provide the correct links for the datastream
version content.
Regards
Steve
