Shopify App Installation Fails

[learn_5opify]

Hello
I have developed a Shopify following the instructions for the Nodejs template.
While I am able to run the app successfully in a development store, I am unable to use the single merchant install link successfully.
When I install the application, I get the error shown in the attached screenshot.
Can you kindly provide any information on what I could be doing wrong?

I'd like to help, but I don't see an attachment to your topic. Could you reply with the attachment or, better, the error message itself?

Sorry for the mixup.
The error message is: "There is no page at this address"

Thanks for getting back to us. Would you mind providing a few more details so we can better look into your issue?

1. What distribution method have you selected for your app?
2. You mentioned "When I install the application." Are you able to successfully install the app, and then you see this error when trying to visit the app's home page? Or do you see this error when installing the app?
