Attribute [mailPreview] does not exist.

[BennyAlex]

Hello,

I added Route::mailPreview() inside routes/web.php and getting the following error:

Attribute [mailPreview] does not exist.

at vendor/laravel/framework/src/Illuminate/Routing/RouteRegistrar.php:93

I already tried clearing the cache.

PHP 7.3.25
laravel 8.27

Same issue here and reported with more info on #68. for me it looks like it has to do something with the php artisan clear-compiled function i run in my deploy scripts.

[m-bosch]

Because i am not the only one perhaps @freekmurze has (almost always) a solution.

[BennyAlex]

@freekmurze can you explain, wh do you close the issues? These is a real bug, so it has its right to stay in issues

[freekmurze]

The tests prove that the package is working. Also, in my projects it is working well.

So, I consider this to be a bug somewhere in your code, and not in the package.

The issue tracker is only for bugs inside the page.

Should you find that the package is in error, submit a PR to fix it.

My problem was solved by checking online php version als CLI version. these were different because of that the wrong package was installed.

@freekmurze
hey, Looks like the installation with composer gets broken?

there is only the src folder, when I try to include "\Spatie\MailPreview\Http\Middleware\AddMailPreviewOverlayToResponse::class," it can't be found.

I already reinstalled it, after upgrading to composer v2. Still only src folder. Maybe your upload is broken? Or which php version do you support? I am using PHP 7.4.3

[m-bosch]

We solved it to remove the route, and register it tlike below in the appserviceprovider

            $kernel->appendMiddlewareToGroup('web', \Spatie\MailPreview\Http\Middleware\AddMailPreviewOverlayToResponse::class);
        }```


also in the route serviceprovider we added some code for the frontendroutes:

if ($this->app->environment('local')) {
                Route::mailPreview('digifactory-mail-preview');
            }


this way it works fine for us.

[BennyAlex]

thanks for response. Can you show the content of your ventor/spartie/MailPreview folder pls? I wonder if you have an http folder there

Not sure if you have already found a solution for this, but this is mine:
In order to make it work, you will have to run composer require spatie/laravel-mail-preview while PHP is running at version ^8.0 locally. When PHP is running on version 7, it will not install the package properly

For me, I had installed the package with composer require --dev which meant that it worked fine in local, but when I migrated to my staging environment, I got the Attribute [mailPreview] does not exist error.

This is because I had Route::mailPreview(); in my routes/web.php file, and mailPreview doesn't exist in Staging if you installed this package with composer require --dev .

The quickest fix for this problem is to move this package from "require-dev" to "require" in composer.json and then run composer install again.
