[Auth/Laravel Breeze] Unclear error message 'TypeError Illegal offset type' for wrong middleware

[pedzed]

I am using Laravel Breeze in combination with a tenancy package. Because I changed the auth middleware to tenant.auth and forgot to change all occurrences, I was stuck for a long time with the following vague and unhelpful error message:

TypeError Illegal offset type

The stack trace and context can be seen here: https://flareapp.io/share/Lm8EXGRP

Upon finding the page https://laravelquestions.com/2021/02/26/larvael-auth-middleware-illegal-offset-type/, I figured out after a while that my middleware is wrong:

// Original:
Route::post('/confirm-password', [ConfirmablePasswordController::class, 'store'])
    ->middleware('auth')
;

// Should have been in my case:
Route::post('/confirm-password', [ConfirmablePasswordController::class, 'store'])
    ->middleware('tenant.auth')
;

Laravel should handle mismatched middleware better.

Addendum:
Apparently auth somehow still exist somewhere, which is why upon removing the period this same error message is not displayed:

Illuminate\Contracts\Container\BindingResolutionException
Target class [tenantauth] does not exist.

Either way, the aforementioned error is really vague and should be improved.

Addendum 2:
I thought perhaps it's because it would take auth in auth.basic, but commenting it out shows that that is not the case. I am not sure what else it could be.

// app/Http/Kernel.php
protected $routeMiddleware = [
    'tenant.auth' => \App\Http\Middleware\Tenant\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    // ...
];
