Mongoose for var in loop in subdocuments

node.js mongodb for-loop mongoose subdocument

Use an indexed for loop, instead of a for … in:

for (let i = 0; i < socialAccounts.length; i++) {    var currentAccount = socialAccounts[i];}

The for … in loop will enumerate additional object properties as you noticed and should not be used for arrays. See this question and answers.

node.js mongodb for-loop mongoose subdocument

Try

.findOne(...() => {})

It worked for me
