update an element inside an array of object is not working in Mongoose

Question

I've the mongoose query to update a document where I've to check the document _id and another id inside an array of object. my query is:

Survey.findOneAndUpdate({"_id":req.params.id,"inv_users.cmp_user_id":cmp_user_id},
{
 $set:{ "inv_users.$.survey_completed":true}
  }

I need to find a document with the _id and update only survey_completed inside inv_users

const SurveySchema = mongoose.Schema({

had this same issue just took out $set all together and it worked

Survey.findOneAndUpdate({"_id":req.params.id,"inv_users.cmp_user_id":cmp_user_id},
{
"inv_users.$.survey_completed":true
  })
