Running the following command on mongo v7.0.5, the error message wasn't clear for me.
Enterprise test> db.test.aggregate([ { $documents: [{ nb: [1, 2, 3] }] }, { $project: { total: { $sum: ["$nb"] } } }] )
MongoServerError: '$documents' can only be run with {aggregate: 1}
I didn't know {aggregate: 1} was the literal expression of a database or cluster-level aggregation.
Could you change the error message to make it more explicit:
MongoServerError: '$documents' can only be run with database or cluster-level aggregation {aggregate: 1}
