Cbc-pillowfight against 7.0-beta Errors

C SDK
1

On my home computers running Ubunutu 20.04 I Installed CouchBase 7.0-Beta.
On a separate machine I downloaded and installed libcouchbase to use cbc-pillowfight against the cluster. But I’m getting a weird error below.
Gave the user Full Cluster Admin access

^Capp1@app1:/etc/apt$ cbc-pillowfight -U couchbase://192.168.1.231/test -u test -P 123456 -I 500000 -B 1000 --json -R --verbose

I also tried

-U couchbase://192.168.1.231/test ._default._default

but just got not a bucket errror.

Went to /opt/couchbase/bin/ on the data node looks like that one works fine. I get ops to the cluster. (BELOW)
I though I followed the steps on docs for Ubuntu 20.04:
https://docs.couchbase.com/c-sdk/current/hello-world/start-using-sdk.html#configuring-apt-repositories-debian-ubuntu
correctly

 ./cbc-pillowfight -U couchbase://192.168.1.231/test -u test -P 123456 -I 500000 -B 1000 --json -R --verbose

I downloaded the [SDK Doctor ] GitHub - couchbaselabs/sdk-doctor: Application-server-side cluster connection diagnostics. on the app node. I can run it if needed. the output is very verbose.

installed CouchBase Server 7.0-beta on the app machine … using /opt/couchbase/bin/cbc-pillowfight to create a load on the cluster.
