Getting Object.keys called on non-object when creating mongoose schema

I've done some research and tried few things, like dropping the collection etc. Nothing has helped.

Code:

MongoClient.saveData = function(schemaDefinition, data, collectionName){
    console.log("Schema definition: "+schemaDefinition+" collection name: "+collectionName);
    var RecordSchema = new mongoose.Schema(schemaDefinition);//{ Email: String, FirstName: String});//({any: Schema.Types.Mixed });
    console.log("Schema created.");
    var RecordModel = mongoose.model(collectionName, RecordSchema);
    console.log("Model created. Inserting in batches.")
    RecordModel.insertMany(data)
    .then(function(mongooseDocuments) {
         console.log("Insertion was successful.");
    })
    .catch(function(err) {
        console.log("Error while inserting to DB.")
    });

The error:

/home/ubuntu/ds_queuesystem/node_modules/mongoose/lib/schema.js:381
  var keys = Object.keys(obj);
                    ^

Schema definition:

var schemaDefinition = "{SCHID: String, Priority: Number, Status: String, Json: Schema.Types.Mixed})";

schemaDefinition should be an Object, not a literal.

Try with:

var schemaDefinition = {
  SCHID: String,
  Priority: Number,
  Status: String,
  Json: Schema.Types.Mixed
};
