[iscsi] [upgrade] [4.x to 5.x] [rhel-8] : target-api and target-gw services are stuck in AttributeError: 'Request' object has no attribute 'is_xhr' : upgrade failed saying Error EINVAL: iscsi REST API failed request with status code 500'
.Upgrade from {storage-product} 4.x to 5.x with iSCSI works as expected
Previously, due to version conflict between some of the `ceph-iscsi` dependent libraries, upgrades from {storage-product} 4.x to 5.x would lead to a persistent HTTP 500 error.
With this fix, the versioning conflict is resolved and the upgrade works as expected.
However, as a result of this fix, iSCSI REST API responses aren’t pretty-printed.
