I'd love to have a functional test for this would you be able to add one? Models are inside src/Laravel/workbench/app/Models.
To run the tests see https://github.com/api-platform/core/blob/4a72073573af0740ffb24c7ed1e8a13e36546654/src/Laravel/CONTRIBUTING.md#tests

API Platform library tries to extract the foreign_key from all relations, but BelongsToMany relations don't have a getForeignKeyName() method, so it returns null. When API Platform tries to flip an array containing null values, PHP throws the error: array_flip(): Can only flip string and integer values, entry skipped.
