I have a fully operational Shopify App written in PHP (using the Laravel web framework). The App has been fully tested and validated on a local host, i.e. all systems are operational. (local hosting is done via npm run dev and everything runs well)
To embed this App in a Shopify store front we have to host it via Heroku. Documentation here: https://shopify.dev/docs/apps/launch/deployment/deploy-web-app/deploy-to-heroku
The hosted app successfully builds in Heroku (deploys) but the resulting domain link only responds with server 500.
Here is my only clue: (I have scrubbed all sensitive info from the Heroku logs --tails):

I have double checked the env files, composer.json, Dockerfile, and nginx.conf.
All of these files seem to be correct.
I have tried several additions to these files but non seem to fix the server 500.
Seemingly the only response from the Heroku logs is a GET 500 from index.php which has been attached:
