[n1ql] query against system:indexes failing with service shut down error

fresh install
2 nodes w/kv,n1ql,index
-the following steps happen in the test setup
the test also clusters these two nodes together
then the test creates an empty bucket
then the test deletes an empty bucket
then the test removes one node from the cluster
then clusters them together again
then the test creates an empty bucket and runs the query

run query
cbq> SELECT * FROM system:indexes WHERE indexes.bucket_id is missing;
{
"requestID": "2295f81f-6bff-41f5-b488-cc390d8ea92f",
"errors": [

{ "code": 1181, "msg": "Service shut down" }

],
"status": "fatal",
"metrics":

{ "elapsedTime": "313.765µs", "executionTime": "186.674µs", "resultCount": 0, "resultSize": 0, "serviceLoad": 0, "errorCount": 1 }

}

not when i do it through the UI it is fine, but through cbq and curl it throws hte service shut down error

attaching logs

this test passes in 7.2.4 and trinity

also the test that runs into this issue is here

./testrunner -i /data/workspace/debian-p0-query-vset00-00-collections_system_7.0_P0/testexec.36507.ini -p bucket_size=256,skip_primary_index=true,skip_load=True,nodes_init=2,GROUP=P0 -t tuqquery.tuq_system_keyspaces.QuerySystemKeyspacesTests.test_keyspaces_basic,force_clean=True,GROUP=P0,bucket_size=256,skip_primary_index=true,skip_load=True,nodes_init=2

it reliably hits the problem but I have yet to come up with a manual reproduction
