laravel 5 development.ERROR - php

Question

Im getting this error randomly,i search it and it seems that this happens if you havent set an app key,the problem is i had set it from the start.The problem usually happens when i make multiple $http calls from my app it never happens from postman.
error:

update:
ok i checked it a little more and if change the app.php
'key' => env('APP_KEY', 'someRandomString')
with my key
'key' => env('APP_KEY', 'My key')
im getting error 404 not found on the route.I think that at some point randomly fails to read the env key.It may be a problem with my resources im developing on my computer i will upload it to a server and check it again.

Answer 1

You should change it in your .env file, when you change the someRandomString in the env() call all you're doing is telling Laravel to use that as a default if it can't find the real app key. So Laravel is probably finding an incorrect app key and never gets to your default.
If you don't have a .env file (but you probably do, since your default failed), you should have a .env.example file that you can rename. Then you can do php artisan key:generate to generate and set it automatically.
If it still doesn't work after doing that, you have some other problem unrelated to app keys. :) Good luck!

Answer 2

OK i solved it the problem was my computer resources was not enough to make multiple calls after i upload to server everything works fine.
