PutDistributedMapCache Flow Routes To Incorrect Relationship

It appears that PutDistributedMapCache 1.15.0 when using the following Controller Services:

CouchbaseClusterService 1.15.0
CouchbaseMapCacheClient 1.15.0

Routes to the FAILURE relationship when it is SUCCESSFUL in its placement of an object in the cache .
I note the attribute added when it is passed to  FAILURE states "cached:failure" however that is very much note the case .

I did consider latency however this is running in a local lab and its about as fast as its going to get.
