We are running Networker 9.1 with vProxy applaince in vCenter and ESXi 6.5. When we are trying to perform instant recovery fails with error message"Virtual machine recovery failed: vProxy recovery failed with error message: Session "e026d1b5-ade6-4b58-97dd-ad8ac276c873" failed. Error: Unable to access the virtual machine configuration: Invalid datastore path 'ds:///vmfs/volumes/1aad0fd4-e2417d3c/xxx_test/xxx_test.vmx'.
