Hi, @antoniopresto

This is the structure of my data stored on my BD:

I need to set a new field on array musicas using the code above but when I tried that code all the data inside array musicas are replaced. Am I missing some step?

You need to use $elemMatch to update a neasted array.
https://docs.mongodb.com/manual/reference/operator/query/elemMatch/

[antoniopresto]

you can use $ to represent the array index you matched: musicas.$.field

None of these solution works
