Illuminate\Contracts\Container\BindingResolutionException: Target [LaravelJsonApi\Contracts\Server\Repository] is not instantiable while building [LaravelJsonApi\Laravel\Routing\Registrar].

[vitkuz573]

When testing my package with Orchestra Testbench, if the getPackageProviders method in TestCase.php specifies the service provider of my package:

protected function getPackageProviders($app): array
{
    return [
        MyPackageServiceProvider::class
    ];
}

The following error appears:

Illuminate\Contracts\Container\BindingResolutionException: Target [LaravelJsonApi\Contracts\Server\Repository] is not instantiable while building [LaravelJsonApi\Laravel\Routing\Registrar].

And at the same time, if I disable the route load (loadRoutesFrom) in the boot method of my service provider, then this error disappears. But of course I will not be able to test any routes.

You'd presumably need to add the Laravel JSON:API service providers to your list of service providers in getPackageProviders(). Because the autoloading of Laravel service providers does not happen in a package.

That solved my problem. Thank you!
