An error occurred while loading the web debug toolbar (500: Internal Server Error). #69

jeremykendall · 2016-09-05T12:46:32Z

After installing the skeleton per the instructions in the README and running COMPOSER_PROCESS_TIMEOUT=0 composer run and visit http://localhost:8888 or http://localhost:8888/index_dev.php I get the following error in a JS alert:

An error occurred while loading the web debug toolbar (500: Internal Server Error).

Do you want to open the profiler?

That error pops up every time I click "OK". When I hit "Cancel" I see the following:

RuntimeException in ArgumentResolver.php line 82: Controller "Symfony\Bundle\WebProfilerBundle\Controller\ProfilerController::panelAction()" requires that you provide a value for the "$request" argument (because there is no default value or because there is a non optional argument after this one).

jeremykendall · 2016-09-10T19:53:29Z

Here are screenshots of what I'm seeing.

fabpot · 2016-09-10T20:17:31Z

What if you run composer up to get the same versions as mine?

jeremykendall · 2016-09-10T20:20:34Z

Same result 😦

fabpot · 2016-09-10T20:59:14Z

I don't really understand how that's possible. Can you add print get_class($resolver)."<br />\n"; after line 55 in vendor/symfony/http-kernel/Controller/ArgumentResolver.php and tell me what it outputs?

jeremykendall · 2016-09-10T21:02:18Z

Silex\AppArgumentValueResolver
Symfony\Component\HttpKernel\Controller\ArgumentResolver\RequestAttributeValueResolver
Symfony\Component\HttpKernel\Controller\ArgumentResolver\RequestValueResolver
Symfony\Component\HttpKernel\Controller\ArgumentResolver\DefaultValueResolver
Symfony\Component\HttpKernel\Controller\ArgumentResolver\VariadicValueResolver

fabpot · 2016-09-10T21:06:24Z

Can you send me a zip of the project (fabien ... symfony.com)? you should have Silex\AppArgumentValueResolver listed here, but for some reasons you don't.

jeremykendall · 2016-09-10T21:18:20Z

Sure thing! It should be on its way now.

fabpot · 2016-09-11T16:15:13Z

@jeremykendall Not received it yet :(

jeremykendall · 2016-09-12T12:44:48Z

Hmmm. Just sent a test email your way to see if it gets through. It's coming from jeremy at jeremy kendall dot net.

Mokto · 2016-12-02T19:57:21Z

I unfortunately get this issue as well. I would be happy to give more information.

Mokto · 2016-12-02T19:58:43Z

But I did git clone / composer install / composer run-script run / navigate to http://localhost:8888/index_dev.php

I am on windows 7 / php 7.1

piotr-sikora-v · 2017-01-02T07:17:39Z

I have same issue.
In log I found:
`

bastien-g · 2017-01-05T09:53:35Z

I had same error, seems to be due to #75
As @allejo pointed out twig-bridge 3.2 fixed it for me.
So I replaced
"symfony/twig-bridge": "~2.8|3.0.*",
by
"symfony/twig-bridge": "~3.2",
in my composer.json and updated with composer.

@bastien-g

Fixes this error: "An error occurred while loading the web debug toolbar (500: Internal Server Error)." by changing the twig-bridge version as suggested by @bastien-g (silexphp#69 (comment)). Resolves silexphp#69

cherifGsoul · 2017-02-17T13:44:59Z

@bastien-g Can you please tell me if you have now an error on the profiling page?

Because with your fix I have an error on index_dev.php/_profiler/529983?panel=request

Update: I cleaned the cache and all is working fine now, so dont forget to clean the cache in var folder after deps update

t-initi · 2017-02-23T16:50:21Z

I had the error after i deployed my app.
The way i resolved it is by doing a clear cache on the deployed app. you can clear the cache of a deployed app by using an ssh connection.

Do you get this error locally(meaning on an app that is on the local server) ?

cherifGsoul · 2017-02-24T21:06:38Z

@t-initi yes I did locally

casenjo · 2017-03-17T17:30:09Z

@bastien-g thanks for that! Fixed the issue right up when running the latest Silex Skeleton (as of today)
