Parse dashboard - objectId must be a string: ObjectIdHex("56eac5ea1ac8242012ae4ed9") - mongodb

Question

Recently i migrated all my parse data to MongoLab. i'm saving documents (parse object) directly to mongoDb using MongoClient.save(...), and not using parse SDK.
now mongo generate auto id, in my case - '56eac5ea1ac8242012ae4ed9', and parse dashboard not show any row in this class till i delete this object (document) and i'm getting the next error: objectId must be a string: ObjectIdHex("56eac5ea1ac8242012ae4ed9")
should i save id differently?
how to convert my id to regular Parse object id? (if i reallty need it?)
any solution?
I know parse dashboard is temporary, but right now it helps

Answer 1

It occurs because by default Mongo create an ObjectId for each object stored in its collections. To overcome it, you have to order Mongo store your own generated Id.
You can do it by sending the _id property in your object that is being stored in Mongo. Something like this:
db.collection('_User').save({_id: yourid, ...})
You can generate any random string id, but it would be good to generate the _id as the same way Parse Server does. If you check Parse Server repository (https://github.com/ParsePlatform/parse-server/blob/master/src/cryptoUtils.js) you can find how the id is generated.
Anyway. There are solutions, like www.back4app.com, that already provides full hosting of both parse server, parse dashboard and database
