Container::getAlias($abstract) throws ErrorException: Illegal offset type in isset or empty when $abstract there is not in $this->aliases[]

Question

• Laravel Version: 5.6.16
• PHP Version: 7.2.3
• Database Driver & Version: N/A

Description:

laravel\framework\src\Illuminate\Container\Container.php public function getAlias($abstract) throws ErrorException: Illegal offset type in isset or empty when $abstract there is not in $this->aliases[]

$this->aliases[$abstract] is null and !isset($this->aliases[$abstract]) throws ErrorException: Illegal offset type in isset or empty

$abstract value is Modules\Administration\Tests\Commands\StubJsonCommandHandler

Steps To Reproduce:

Run AdministrationControllerTest (https://github.com/proyectotau/TAU/ clone laraveldusk branch [4ef9b0e124657abed7afde0969f332bf7be95a8b])

Is it a bug or I have any mistake? Thanks in advance!

When binding an instance to the container, please make sure you are using:

app()->instance('dependency', $instantiation);

not,

app()->bind('dependency', $instantiation); // DON'T bind an instance

Attempting to bind an instance will result an error, as the container tries to index possible aliases using a concrete object as opposed to a type.
