Illuminate\Contracts\Container\BindingResolutionException: Target [CloudCreativity\JsonApi\Contracts\Http\Requests\RequestInterface] is not instantiable.

Could somebody explain me the reason why this could happen? I'm trying to integrate laravel-json-api in an existing project (switching from limoncello-collins, since he gave up developing for laravel...) . When I tried the demo-laravel-json-api project I had no problems.

RequestInterface is only bound into the container if there is a valid JSON API request. This happens in the json-api middleware here:
https://github.com/cloudcreativity/laravel-json-api/blob/master/src/Http/Middleware/BootJsonApi.php#L82

Have you used the json-api middleware? It's intended for use in the route group that defines your resources, as per here in the demo app:
https://github.com/cloudcreativity/demo-laravel-json-api/blob/master/app/Http/Kernel.php#L51

Daaaamn.... Thanx for the middleware hint... I was running my (unit) tests with the WithoutMiddleware trait ... ;)
