Expected behavior of a query like this
db.a.aggregate([{$project: {_id: 0, result: {$sqrt: [NaN]}}}])
is to return the following for each document in the collection
{ "result" : NaN }
This $project does not get pushed down to SBE until the SBE Pushdown feature (PM-3162), which is still in progress. Working on this feature, the above $project does get pushed down to SBE and fails with this assertion:
uncaught exception: Error: command failed: {
"ok" : 0,
"errmsg" : "PlanExecutor error during aggregation :: caused by :: $sqrt's argument must be greater than or equal to 0",
"code" : 7157710,
"codeName" : "Location7157710"
} with original command request: {
"aggregate" : "sqrt",
"pipeline" : [
{
"$project" : {
"_id" : 0,
"result" : {
"$sqrt" : [
NaN
]
}
}
}
],
"cursor" : {
},
"lsid" : {
"id" : UUID("5494ede8-1225-47e6-9396-7975688eaf2a")
}
}
This assertion was introduced in 6.3.0-rc0 by SERVER-71577.
