org.nrg.xft.exception.InvalidValueException: URI references data outside of the project

[Tom Doel]

I'm making the following REST call to populate the catalog with scan types etc based on the existing DICOM data:

  PUT https://<myserver>/data/archive/projects/<projectname>/subjects/<subject>/experiments/<experiment>?pullDataFromHeaders=true

On our production server this fails with the following exception (restless.log):

2016-07-07 10:39:04,634 [http-bio-8080-exec-2023] ERROR org.nrg.xnat.restlet.resources.SubjAssessmentAbst -

But it works on our test server. The main difference between the servers is that the production server uses the apache proxy to handle the https.

Possible related issue?

But I don't know why the proxy would make a difference to this REST call when other calls seem to work...
