📚 Description
To improve DX, we should ensure that the responses are strings or implement the Stringable interface (which was added in version 8.0 of PHP).
This was already being done accidentally, but now the code makes sure of it and throws a very clear exception to the developer if this is not the case.
This allows for more flexibility, for example, if someone is doing a simple CRUD, they could directly respond with their models in their controllers as long as they implement the Stringable interface (leaving aside opinions on whether this is more or less correct).
