Correlated Subqueries

Working with Data

I’m trying to perform a correlated subquery as described here: https://docs.mongodb.com/manual/reference/operator/aggregation/lookup/#perform-a-concise-correlated-subquery-with--lookup

I’m getting the following error: $lookup with 'pipeline' may not specify 'localField' or 'foreignField'

I’m on version 5.0.2, so according to the documentation, this should work. Is anyone else having a problem with this?

Thanks

Please share the exact $lookup you are doing. It is hard to tell what is wrong without seeing it.
