Map Reduce view - returning data in couchbase but not returning data in python

Python SDK

HI,
I created a couchbase map reduce view, published it to production & tested the view, it returns me 4 rows. The view has only map part as below:
Couchbase View

function(doc) {
	if (doc.t == "memGroupsTest") {
		if (doc.memGroupMems) {
			for (i=0; i < doc.memGroupMems.length; i++) {
				if (doc.memGroupMems[i].requestSentTs == 0) {
					emit(doc.memId, doc.groupId, doc.groupName, doc.memGroupMems[i].groupMemId, doc.memGroupMems[i].allowTrainNotifications);
				}
			}
		}
	}
}

The following is the Python code

from couchbase.views.params import Query
		try:
			print("In...")
			#cb is my bucket object
			rows = self.cb.query("_design/dev_myDev", "pending", include_docs=False)
			print(str(rows))
			for row in rows:
				print(str(row.key))
			print("Leaving...")
		except Exception as e:
			print(str(e))

The following message gets printed on console:

<RC=0x3B[HTTP Operation failed. Inspect status code for details], HTTP Request failed. Examine 'objextra' for full result, Results=1, C Source=(src/http.c,144), OBJ=ViewResult<rc=0x3B[HTTP Operation failed. Inspect status code for details], value=None, http_status=400, tracing_context=0, tracing_output=None>, Tracing Output={":nokey:0": null}>

I had also tried the following…still getting zero rows.

from couchbase.views.params import Query
....
....
....
			q = Query()
			q.limit = 10
			rows = self.cb.query("_design/dev_myDev", "pending", include_docs=False, query=q)

The same view is returning data when queried in couchbase, but zero rows when queried in python.
Am I missing something???

Thanks ,
Sachin
