Hi there,

Thanks for creating this excellent package.

I tried to follow the tutorial at https://dev.to/area17/getting-started-with-blast-storybook-for-laravel-blade-c5c but encountered difficulties.

Steps I tried:

• composer require area17/blast
• php artisan blast:launch
• create resources/views/stories/button/primary.blade.php with the content the tutorial ask me to create

Visit http://localhost:6006/?path=/story/button--primary

Get the following error message:

In my console where php artisan blast:launch is running, I get

As a side note, similar errors still happen when I do php artisan blast:demo and visit those sample components

If you could point me to a better direction to resolve this issue, that would be great.

@ziming It looks like it's unable to find your views or there's an error within them.

Does anything render when you go to http://[your-laravel-app-url]/storybook_preview/button/primary? This is the url which Storybook uses to render your component within its UI. You can find it in the 'Network' tab of your dev tools when filtering by 'Fetch/XHR`.

If that doesn't fix it, do you have a repo you can link me to and I'll take a look?

Any solution? I have the same problem.

@ziming @mrtimbroo I found the source of the problem, when creating a new project in laravel, I changed the APP_URL to APP_URL=http://localhost:8000, then after running composer require area17/blast, I called the command php artisan vendor:publish --provider="A17\Blast\BlastServiceProvider" --tag="blast-config".

But after that, I still had problem with preview after calling php artisan blast:launch.

opening the developer locks, I got the following message

he even said I have a problem with CORS.

After following this tutorial, I restarted the server with php artisan serve and I was successful

v1.0.0

with v1.3, I didn't need to add CORS.

I had the same problem. Setting correct APP_URL in .env file solved a problem.
