YCSB workload e with wrong n1ql syntax 100% memory is consumed

Attached the couchbaseclient Couchbase2Client.java.txt file for YCSB. If we run this with command,

bin/ycsb run couchbase2 -s -P /root/perfrunner-ycsb/YCSB_0/workloads/workloade -jvm-args=-Dcom.couchbase.connectTimeout=300000 -jvm-args=-Dcom.couchbase.kvTimeout=60000 -p couchbase.bucket=bucket-1 -p couchbase.host=172.23.100.191 -threads 30 -p recordcount=20000000 -p couchbase.password=password -p maxexecutiontime=600 -p operationcount=10000000 -p couchbase.upsert=true -p couchbase.boost=16 -p couchbase.epoll=true -p couchbase.kv=false -p exportfile=/tmp/ycsb_log/workloade/120_1node/ycsb_log_0.txt -p hdrhistogram.percentiles=80,99,95,50

it throws exception :exception.txt

Wrong query used: SELECT bucket-1 FROM `bucket-1` WHERE meta().id >= $1 LIMIT $2 ( missing `` around bucket-1)

Memory consumption keeps on increasing . It reached 99% . System becomes unusable.
logs attached n1qloutput.zip .

how to repro:
Change couchbaseclient file with the attached , and workloade with kv=false.

version:
happening in 4.6 and 5.0 as well
