Illuminate\Contracts\Container\BindingResolutionException: Target class [bindings] does not exist.
Previous versions of Laravel registered a bindings
middleware in the HTTP Kernel api
group. Starting with Laravel 8, this middleware is registered by its class name using a static class constant instead of a string.
While this change is automated by the Laravel 8.x Shift, if you upgraded manually or have other references within your application, you may still have string references to the bindings
middleware.
To resolve this error, change any string references from bindings
to \Illuminate\Routing\Middleware\SubstituteBindings::class
in your app/Http/Kernel.php
. While uncommon, be sure to replace this for any additional references to this middleware within your application as well.
