Problem with Elasticsearch connector in CB5 beta

I’m getting this error try to XDCR to the couchbase-elastic plugin.

I know i’m connecting to the couchbase jetty service hosted in the ES plugin, as i was getting auth problems to http://localhost:9091/pools which i’ve now resolved.

2017-09-05 21:18:16 127.0.0.1:Can’t get nodes information for cluster 127.0.0.1:9091, err=Failed on calling host=127.0.0.1:9091, path=/pools/nodes, err=, statusCode=404

From what i’ve read in the CAPI server docs (https://github.com/couchbaselabs/couchbase-capi-server) CB should be making a call to localhost:9091/pools/default (which works) and the following which gives.

Adams-MBP:elasticsearch-5.4.2 adamhawkins$ curl -u Administrator:qwaszx http://127.0.0.1:9091/pools/default/buckets/cbpass

Since ES plugin appears to be responding as expected i can only assume its a CB5 beta problem though i’ve not tried 4.x .
Could there be a setting that i’m missing thats trying to access ‘nodes’ rather than ‘default’

For clarity . this error is seen the XDCR screen , i have a remote cluster defined on 127.0.0.1:9091 and a remote replication setup from bucket called ‘pass’ to ES index called ‘cbpass’.

It repeats this error 10 times and i cant get any further logging out.

I can see only 1 document in the ES cbpass bucket
