Responder version: 3.0.5 Laravel version: v5.5.45

In the config file, the documentation for filter_fields_parameter says:

The package can automatically filter the fields of transformed data from a query string parameter configured below. The technique is also known as sparse fieldsets. Set it to null to disable it.

However, when setting it to null I started getting Array to string conversion errors when I sent any query parameters.

I think the cause is here:

$this->app->bind(TransformBuilder::class, function ($app) {
            $request = $this->app->make(Request::class);
            $relations = $request->input($this->app->config['responder.load_relations_parameter'], []);
            $fieldsets = $request->input($app->config['responder.filter_fields_parameter'], []);

            return (new TransformBuilder($app->make(ResourceFactoryContract::class), $app->make(TransformFactoryContract::class), $app->make(PaginatorFactoryContract::class)))->serializer($app->make(SerializerAbstract::class))
                ->with(is_string($relations) ? explode(',', $relations) : $relations)
                ->only($fieldsets);
        });

I've set a xdebug breakpoint after the fieldsets and relations are parsed, and apparently sending null as the key returns the whole request input, as opposed to what I assume was the intended effect of an empty array.

Here is a screenshot of the debugger. What you see in the $fieldsets array is essentially the whole parsed query string:

I can fix this in my project by overriding that method in the service provider, but it still seems like a bug.

Hey! This does indeed seem like an error. I'll look into it, thanks
