App Proxy Error - There was an error in the third-party application

[Devs]

Hi, I'm following the tutorial (https://github.com/ohmybrew/laravel-shopify) to publish the proxy app in the store, but I get an error.

• I am using laravel forge for deploy my app (the app is the same of the tutorial),

• I have configured the Nginx file and I removed add_header X-Frame-Options "SAMEORIGIN";

• The public/.htaccess file is by default use laravel apps.

• I have configured app proxy in shopify correctly.

  prefix: a
  path: laravel-forge
  url shopify shop https://dmodaencali.myshopify.com/a/laravel-forge
  url my app proxy : https://customizesuit.com/proxy

• I have installed SSL.

But I still have an error, I do not know what else to do

This is the error
There was an error in the third-party application

Thanks for the help, thank you very much

Hi @Devs,

It looks like you were able to resolve this, as your proxy page is now showing content. Can you update your post with the solution for other users that may encounter a similar issue?

I know that this error has occurred in the past for not supplying the proper content-type header (Application/Liquid), and not specifying a content-length header value.

Cheers,

Hi everybody.

The problem was that I did not have my SSL certificate properly configured on the server.

You must verify that the certificate is well configured, you can validate them at https://www.sslshopper.com/ssl-checker.html.

You must verify that the router returns the headers correctly content-type header (Application / Liquid) and not specifying a content-length header value.
