CBQ Out of key validation space Error

Couchbase Server
1

Hello I am trying to run this query to move some information from one bucket to another.
/opt/couchbase/bin/cbq -u Administrator -p xxx --pretty=false --file=ss.txt -o found.txt
ss.txt content is:

\SET -max_parallelism 512;
\SET -timeout 1440m;
\SET -txtimeout 1440m;
\SET -scan_wait 0;
\SET -kvtimeout 1440s;
\SET -scan_consistency not_bounded;
\SET -pipeline_batch 20000;
\SET -pipeline_cap 20000;

UPSERT INTO YYY.YYY.YYY(
KEY prop,
VALUE {“property”: TRUE}
)
SELECT DISTINCT prop
FROM XXX.XXX.XXX
WHERE property IS NOT MISSING

But I got error

{
“requestID”: “6cc9b9f0-7507-4edb-bbbd-xxx”,
“signature”: null,
“results”: [
],
“errors”: [{“code”:5006,“msg”:“Out of key validation space.”},{“code”:5006,“msg”:“Out of key validation space.”},{“code”:5006,“msg”:“Out of key validation space.”}],
“status”: “fatal”,
“metrics”: {“elapsedTime”: “3h51m48.175057357s”,“executionTime”: “3h51m48.174928867s”,“resultCount”: 0,“resultSize”: 0,“serviceLoad”: 0,“mutationCount”: 540629506,“errorCount”: 3}
}

I already increase scan_timeout and request-size-cap but it does not effect.
I don’t want to chuck or split query with where condition.

How can I increase key validation space or fix problem?

Thanks.
