Goals

When I forget that a data field is required and try to write null to it, I want the error message to mention the 'data' type.

Expected Results

Expecting an error with the following message:

> RequiredTypes.dataRequired must be of type 'data', got 'null' (null)

Actual Results

I'm getting an error with the following message:

> RequiredTypes.dataRequired must be of type 'binary', got 'null' (null)

Or actually - I would love if "data" was called "binary" as it's so hard to tell apart from "dat*e*".

Steps to Reproduce

1. Create a realm with a schema that has a required "data" property.
2. Try to write a null to an object in that field.

Code Sample

const Realm = require('realm');
const realm = new Realm({
  schema: [
    { name: 'TestClass', properties: { requiredData: 'data' } }
  ],
  path: 'required-data.realm',
});
realm.write(() => {
  realm.create('TestClass', { requiredData: null });
});
