Unsupported projection mongodb in nodejs-CodePudding

my code is :

result = await mongoDBO.collection(collectionName).find({id: data.id},{projection : {'_id' : 0}}).toArray();

But I get the following error

Unsupported projection option: projection: { _id: 0 }

CodePudding user response：

Remove projection property. Just send the projection object:

result = await mongoDBO.collection(collectionName).find({ id: data.id }, { '_id': 0 }).toArray();

CodePudding user response：

I also tested this way and it worked

await mongoDBO.collection(collectionName).find({id:data.id}).project({'_id' : 0}).toArray()
