read nested JSON with the .find() Method-CodePudding

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?

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