Deploying shopify app in netlify but not working

hello, I have developed the Shopify app using the Shopify PHP app template,

after completing development, I tried to deploy the app on Netlify.com,

and deployment is done successfully.

from Netlify, Netlify access the App via GitHub repository.

i have Import App repository in Netlify

but when I run the Netlify domain it gives an error,

also I have added the Environment Variable in Netlify

In my local system, I run the app using the “npm run dev” command. It creates the Cloudflare tunnel, and I copy that tunnel and paste it to the browser and my app was run, but how to set up this kind of URL in Netlify?

Example : https://reveals-cooperation-diamond.trycloudflare.com?shop=mysite.myshopify.com&host=bmNvZGVzaG9wLm15c2hvcGlmeS5jb20vYWRtaW4

please let me know what mistakes I do here. so that my App was not run?

What should i need to add in Publish directory,

field?

Have you managed to make it work, I’m trying to deploy it too and I’m having the same issue as you
