JSON:API Serializer returns null for records of unknown type (instead of ignoring them)

Reproduction

Github repository with reproduction: https://github.com/maxymczech/ember-data-crash-test

Description

Whenever we add new model type to the API, the older versions of the app start crashing upon encountering new model types. For now, I was able to solve this issue by adding the following code to application serializer:

import JSONAPISerializer from '@ember-data/serializer/json-api';

export default class ApplicationSerializer extends JSONAPISerializer {
  normalizeFindAllResponse() {
    const payload = super.normalizeFindAllResponse(...arguments);
    return payload && {
      ...payload,
      data: (payload?.data || []).filter(Boolean)
    };
  }
}

Versions

-- ember-source@3.26.1
-- ember-cli@3.26.1
-- ember-data@3.26.0

@maxymczech that's not an unknown model type, it seems you literally tried to supply null to the store as the data. I'd check that your serializer output is correct.

Edit: I see better now, the JSON:API serializer is returning an invalid response for those records.
