Shopify app - There’s no page at this address

[James-Johan]

I am facing a strange issue, When I installed the app for the first time on a test store, the installation went smoothly but after re-installation after OAuth, Shopify kept showing me the following:

"There’s no page at this address".

I'm using the node.js template.

I would like someone here to shed some light on the issue.

Hey @James-Johan!

It seems like there could be a few possible reasons why the issue is occurring, but without further information, it's hard to give a definitive solution. Here are some steps you can take to troubleshoot:

• Check if the app is installed on the Shopify store. Sometimes, re-installing the app doesn't work due to the residual files or cache that are still in the store's system. Make sure that the app is fully uninstalled before re-installing it again.
• Check if the redirect URI is correct in the OAuth flow. Ensure that your redirect URI is set up correctly in your Shopify Partner Dashboard, and the Node.js app code is using the correct URI for the OAuth flow.
• Check the callback function in the Node.js app. If you're using the Node.js template, there may be an issue with the callback function in your app code. Check if it's pointing to the correct Shopify API endpoint and if there are any errors that need to be fixed.
• Check the logs to look for any errors. Sometimes, the error message can give you a clue as to what's going wrong. Check the logs in your Node.js app to see if there are any errors related to the issue that's occurring.
• Try using a different browser or incognito mode. It's possible that the issue could be related to a browser or cache issue. Try using a different browser or incognito mode to access the Shopify store and install the app.

If none of these steps solve the issue, you may want to reach out to Shopify Partner Support for further assistance with the installation process.

Hi Moira, thanks for your response!

I checked and verified the above and still got the same error.

Once the application is installed, the app's homepage is displayed for a second and the 404 error appeared. I added additional logs that should audit every execution of the API methods, and I didn't see any log line related to OAuth callbacks.

Please see below the error.

Hey James-Johan, I have exactly the same problem as you. It is also displayed for 1 second the app and then comes the error as with you in the screenshot.

The strange thing is also that when I install the production app under "Test you app" in a development store, then it works.

Does anyone have a solution for this?
