You make some changes, now my apps got lot of error

I did use all webman original file but now I got error Eloquent
`Error: Call to a member function connection() on null in /home/public_html/test/roemahmedia/vendor/illuminate/database/Eloquent/Model.php:1653`

and some other error that my app cannot run

Start by reproducing the reported Eloquent error and inspect vendor/illuminate/database/Eloquent/Model.php at line 1653, using the reported application setup. Compare the original webman files with the changed application and identify the cause of the null connection; done means the app runs without this error or the other reported startup errors.
