Unexpected error: attribute.split is not a function

[whollacsek]

Expected behavior

Should not throw error while creating a new row from the Forest UI.

Actual behavior

Can not create new row in table because of TypeError: attribute.split is not a function in https://github.com/SeyZ/jsonapi-serializer/blob/b0315e95e6156395590094c3c48fce6e3c75bf95/lib/serializer-utils.js#L293, see stack trace below.

If I add a console.log(attribute) to see what's being passed I get:

id
[ 'id',
  'createdAt',
  'name',
  'type',
  'account',
  'attributReportAttributes' ]
<STACK TRACE>

Somehow an array was passed over instead of the content (?) of the array.

This is a brand new project I just generated using the Docker image, no further modifications were applied.

Context

Project was created using the Docker method.

• Package Version: "^6.0.0",
• Express Version: "~4.16.3",
• Sequelize Version: "~5.15.1",
• Database Dialect: Postgres
• Database Version: 12

I think I have an idea why this is happening...

Problem

If my understanding is correct there is a fatal flaw in the logic of the serializer: https://github.com/ForestAdmin/forest-express/blob/2784cf8a1aa2fe4bdc13ccbe324a9e1b5d3563be/src/serializers/resource.js#L152

The serializationOptions object contains an attributes key that should hold an array. However when getAttributesFor(serializationOptions, schema.fields) is called, if the database schema has a table called attribute it'll be serialized into attributes thus overriding the initial attributes field in the serializationOptions object.

Solution

It would be the best to group all database schema related attributes into a separate field in serializationOptions instead of injecting them right at the root.

I had the same probleme, I hade to change the table name to make it work
