Given select greeting qry example with REST API (without statement= in -d) in the doc is not working

It has been observed that the document in 6.5 given below statement is not working as mentioned and is getting "msg": "No statement provided".
But works fine after providing the -d 'statement ..' (https://docs.couchbase.com/server/current/analytics/run-query.html)

I am not sure if this is a documentation issue or a regression from earlier versions. If no issue from Analytics REST API, then this should be fixed in the documentation.

Tested on Enterprise Edition 7.0.0 build 2465.

--------
In the documentation:
"For example, you can run the query SELECT "Hello, beer!" AS greeting through curl:

$ curl -u Administrator:password -d 'SELECT "Hello, beer!" AS greeting' http://localhost:8095/analytics/service

The request returns:

{
"requestID": "f1b8451c-f626-46be-b1f8-e9ffc891550b",
"signature": "*",
"results": [

{ "greeting": "Hello, beer!" }

]
,
"status": "success",

{ "elapsedTime": "28.292741ms", "executionTime": "24.82841ms", "resultCount": 1, "resultSize": 31, "processedObjects": 0 }

}
"
