Couchbase with Apache Camel

I’m using Red Hat Studio Developer to connect with Couchbase.

According to https://camel.apache.org/components/latest/couchbase-component.html, the URI follows this format couchbase:protocol:hostname:port, then I connect with the URI couchbase:http:localhost:8091?bucket=Transcoding&password=xxxx&username=xxxx

Then my console shows me this error:

13:38:18.470 [main] ERROR o.s.boot.SpringApplication - Application startup failed org.apache.camel.RuntimeCamelException: org.apache.camel.FailedToCreateRouteException: Failed to create route Technical at: >>> To[couchbase:http:localhost:8091?bucket=Transcoding&password=xxxx&username=xxxx] <<< in route: Route(Technical)[[From[direct:technical]] -> [Bean[ref:_bean… because of Failed to resolve endpoint: couchbase://http:localhost:8091?bucket=Transcoding&password=xxxx&username=xxxx due to: Invalid URI. Format must be of the form couchbase:http[s]://hostname[:port]/bucket?[options…]

Based on the error, I change the URI to:
couchbase:http://localhost:8091/Transcoding?password=xxxx&username=xxxxx

Then my console shows me this error:

I am pretty sure that bucket exists and the user and password are correct.
What could be happening? Am I doing something wrong?

Thanks.
I hope for your help.
