Basic Join issue

I’m trying to replicate the lookup from the video but I’m getting the below warning. What am I missing ?:confused:

Expected “[” or AggregationStage but “{” found.

{
from: ‘comments’,
let:{‘id’,’$_id’},
pipeline :[
{’$match’:
{’$expr’:{’$eq’:[’$movie_id’,’$$id’]}}
}
],
as: ‘movie_comments’
}

Hi @Gowtham_Manoharan_21823,

Please look at the post:

Let me know if you need further information.

Thanks Kanika. I finally figured out my mistake. I had put a , instead of : in the let array :man_facepalming:

It happens! :smiley:

Good Luck!
