Hi!  I am new here... But my project was working normally since yesterday when I deployed an updated code and I start to receive this Message: 

This page isn’t working

.appspot.com is currently unable to handle this request.

HTTP ERROR 500

For me it is really weird because I just change a label.  And when I am going to my app engine panel and I am trying to access a old version app, this old version is working.

Could someone help me with this?

I am using PHP Laravel / BigQuery

This could be due to a number of reasons. I would recommend you to check your logs which will provide you with more information about what’s causing the issue. You can check your logs by going on App Engine> Versions> Tools (under diagnose) -> logs.

I found the problem, And I will answer my own question because maybe someone could be with the same problem...

I tried to deploy after this error and do some changes, but I was after that this error:

gcloud app deploy --promote

File upload done. Updating service [default]...failed. ERROR: (gcloud.app.deploy) Error Response: [9] Cloud build bfe8bf5b-8368-4db6-a64e-8272d269ed76 status: FAILURE.

''' ''' '' \"url\": \"https://api.github.com/repos/doctrine/inflector/zipball/ec3a55242203ffa6a4b27c58176da97ff0a7ae.

I read this message:

"errorMessage":"INFO     FTL version php-v0.17.0\nINFO     Beginning FTL build for php\

So I tried to do a composer update, and run php artisan serve, and in both cases the same error:

In Finder.php line 602:

  The "" directory does not exist.  

So, I thought to take a look into my /config folder, and to my surprise this folder disappears!

therefor, I needed to recreate the folder with all files and run again composer install.

After that, I could run again the php artisan serve and I could do the deploy:

gcloud app deploy --promote
