MongoDB Realm BadChangeSet Error: failed to validate upload changesets: ProtocolErrorCode=212

Question

I am new to MongoDB Realm, however had some experience with MongoDB.

Before any comments about the same problem, I already have been to all discussions and nothing have helped me yet.

I have consulted these discussions:

Android BAD_CHANGESET(realm::sync::ProtocolError:212): Bad changeset (UPLOAD) Error

Keep getting BadChangeset Error

But sadly, either the mentioned solutions doesn’t work for me or I am not able to understand those.

I am currently using Realm in Nodejs. I have partition key as restroName while activating sync. But constantly I keep getting 212 error while I connect using:

const realm = new Realm({
        schema:[ItemSchema],
        sync:{
            user:user,
            partitionValue: user.id,
        }
    })

failed to validate upload changesets: SET instruction had incorrect partition value for key “restroName” (ProtocolErrorCode=212)

When I try to use partionValue: “anything”, it gives:

user does not have permission to sync on partition (ProtocolErrorCode=206)

So I assume it needs to be the user.id on the partitionValue but I want to store data in the realms with restroName.

Also I always clear the realm data (wipe it) before I make changes.

I hope I can get help.

Update: My Item Schema looks like this:

const ItemSchema = {
    name: "item",
    properties: {
      _id: "objectId",
      restroName: "string",
      details:  "string?",
      name: "string?",
      status: "string?",
      price: "string?"
    },
    primaryKey: '_id'
}

The problem raised because I messed partitionKey as user id and restroName. The way I solved it was I kept the partitionKey as restroName and under permissions I kept the template none and set partitions for read and write in realm as :

{
  "%%partition": "%%user.customData.restroName"
}

I consulted here to enable custom data.
