HELP: Uncaught Error: Class 'Crawler' not found

greghaygood · December 28, 2017, 6:08am

Hi! I downloaded the latest 4.0.1 self-hosted zip to evaluate I.N. for a client, and am getting this error:

PHP Fatal error:  Uncaught Error: Class 'Crawler' not found in /opt/ninja/app/Exceptions/Handler.php:53
Stack trace:
#0 /opt/ninja/vendor/laravel/framework/src/Illuminate/Foundation/Console/Kernel.php(320): App\Exceptions\Handler->report(Object(Dotenv\Exception\InvalidFileException))
#1 /opt/ninja/vendor/laravel/framework/src/Illuminate/Foundation/Console/Kernel.php(123): Illuminate\Foundation\Console\Kernel->reportException(Object(Dotenv\Exception\InvalidFileException))
#2 /opt/ninja/artisan(35): Illuminate\Foundation\Console\Kernel->handle(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))
#3 {main}
  thrown in /opt/ninja/app/Exceptions/Handler.php on line 53

This happens both via web and using any artisan command. I tried commenting out the Crawler references, but then get a similar message regarding class Utils. I’ve tried the various suggestions via the Troubleshooting section and others from the forums and github issues, but no luck. I tried using a zip from github as well, but same thing.

This is a brand new install on a Ubuntu 16.04 system, using php 7.0.26.

Any other suggestions on what I might be missing?

Thanks!

Did you try running composer install after downloading the code from GitHub?

greghaygood · December 28, 2017, 8:12am

I didn’t think that was necessary with the self-hosted ZIP, but I just tried it and get the same error:

It’s just needed with the code from GitHub.

Can you post the error you see when commenting out the crawler references.

Have you tried running chmod -R 777 storage then chmod -R 755 storage, it also may help to delete bootstrap/cache/services.php if it exists.

greghaygood · December 28, 2017, 8:26am

I commented out the Crawler refs, flipped the permissions and tried again:


gjh@restya:/opt/ninja$ php artisan optimize
PHP Fatal error:  Uncaught Error: Class 'Utils' not found in /opt/ninja/app/Exceptions/Handler.php:72
Stack trace:
#0 /opt/ninja/vendor/laravel/framework/src/Illuminate/Foundation/Console/Kernel.php(320): App\Exceptions\Handler->report(Object(Dotenv\Exception\InvalidFileException))

#3 {main}
  thrown in /opt/ninja/app/Exceptions/Handler.php on line 72

Then I deleted the bootstrap/cache files, but get the exact same error as above.

hillel · December 28, 2017, 8:53am

I’m not sure why you’re seeing the error, the Utils class should be included here:

https://github.com/invoiceninja/invoiceninja/blob/master/app/Exceptions/Handler.php#L18

You can try commenting out this section of code:

https://github.com/invoiceninja/invoiceninja/blob/master/app/Exceptions/Handler.php#L72

greghaygood · December 28, 2017, 10:29am

Ah, so clearing that out yielded a new error:


gjh@restya:/opt/ninja$ php artisan optimize

I indeed did have an unescaped value in my .env file, so that error must not be getting trapped and thus breaking the app. Once I quoted the value (MAIL_FROM_NAME), the app loads and I can proceed with my evaluation.

Would you like me to file a bug report? I haven’t done anything in Laravel so not sure (how quickly) I could help with a PR.

Thanks for helping me through this!

hillel · December 28, 2017, 7:29pm

This isn’t a bug, the .env file doesn’t support having spaces.

hillel · December 29, 2017, 1:14am

Hmm… maybe it is a bug, you should see the .env error not the ‘Crawler not found’ error.

We’ll look into it.

greghaygood · December 29, 2017, 4:18am

Yeah, I only meant the bug was that the true error is getting swallowed. It took me many hours to eventually figure out my simple problem.

Thanks again!

hillel · December 30, 2017, 5:01am

Sorry for the wasted time! Hopefully the awesomeness of the app makes up for it

We’ve checked in a fix which will be included with our next release, at least your efforts will help others.

greghaygood · December 30, 2017, 5:07am

Excellent, glad I could help!
