read nested JSON with the .find() Method

I'm stuck at reading out nested JSON elements that were saved in a MongoDB. I'm trying it with the following method:

blockChainModel.find({"transactions.user": "eltaieyo"}, null, {projection : { transactions: {user : 1}} }, (err, blocks) => {
            if (err) console.error("Cannot find the specified Blocks");
            console.log(blocks);
});

The JSON in the MongoDB, that I'm trying to read looks like this: JSON Image

I want to read out the "transactions" section, and this is what the current method in my Code does: OUTPUT Image

Maybe It is reading them out but my method doesn't give them out correctly?

Solution

  • How about remove projection and try again to check if there is actually some data return ?
