got this error while trying to export pipeline to JAVA
Unrecognized option to $lookup: let
Any clue???
[{lookup: {
from: 'comments',
let: {'id': '_id’},
pipeline: [
{’$match’:
{
‘$expr’:{’$eq’: [’$movie_id’,’$$id’]}
}
}
],
as:‘movie_comments’
}}]
Please try using $lookup instead of lookup.
[{ $lookup: { from: 'comments', let: {'id': '_id’},
Edit:
Also, might want to use $_id as the value in let.
'let': { "id" : "$_id" },

That’s right. It was typo
Also, need to uncheck little checkbox “Use Builders” in compass to generate JAVA code
That solved my problem too, thank you for the sugestion
