Hi!

Im trying to deploy my Laravel app to Heroku with this guide: https://devcenter.heroku.com/articles/getting-started-with-laravel

But when execute git push heroku master i have this problem in console:

im tryed to reinstall Telescope and Telescope Toolbar, or remove them because i saw that error, but no have solution...

its my first time to deploy a laravel app to heroku.

if you need some files from my project to detect the problem tell me

PD: In other forums they told me to run php artisan optimize on console, but it also shows me another error that I don't know how to fix. I don't know if it will affect the main problem. This is the error:

 php artisan optimize  
Configuration cache cleared!
Configuration cached successfully!
Route cache cleared!

   LogicException
