If you use the explain command for a cluster delete on a shardsvr mongod, you get an error. However if you run the same command without the explain on a shardsvr mongod it works.
Code to reproduce the error:
(function() {
const kDBName = "foo";
const kCollName = "bar";
const st = new ShardingTest({mongos: 1, shards: 1, config: 1});const clusterCommandsCases = [
// This does not error
//{cmd: {clusterDelete: kCollName, deletes: [{q: {}, limit: 0}]}},
// This errors
{cmd: {explain: {clusterDelete: `${kCollName}`, deletes: [{q: {}, limit: 0}]}}}
];
assert.commandWorked(st.s0.adminCommand({enablesharding: kDBName}));
assert.commandWorked(st.s0.adminCommand({shardcollection: kDBName + "." + kCollName, key: {a: 1}}));
for (let testCase of clusterCommandsCases) {
assert.commandWorked(st.rs0.getPrimary().getDB(kDBName).runCommand(testCase.cmd),
tojson(testCase.cmd));
}
st.stop();
})();
