I am still getting this error below saying that PHP extension mbstring is missing when deploying my Laravel application (version 6.17.1) using Dokku (version 0.18.3) even though I have followed the documentation (https://devcenter.heroku.com/articles/php-support#using-optional-extensions).

Any help is appreciated, thanks!

Issue solved, here are the steps:
- Make sure your app uses these 2 buildpacks:
https://github.com/heroku/heroku-buildpack-apt
https://github.com/heroku/heroku-buildpack-php
- Create a new file
Aptfileon root directory with content as below:
libonig-dev
libonig4
git add,git commitand deploy, it should work now
