I'm trying to get the differences from a branch version and the Default. When I try differences (GET) from the rest end point of the branched version (https://myserver/server/rest/services/ServiceName/VersionManagementServer/versions/versionGuid/differences) I get the following error:
success: false
error:extendedCode: -2147220219
message: User does not have privileges to perform this operation.

Parameters:

Notable info:

Anyone know how to resolve this error?
