Hi everyone,

I’ve created a new Shopify Remix template app, but the server isn’t starting. When I run npm run dev or shopify app dev, I encounter an error. I’ve attached the error message below for reference.

Hey @Ahsan_Ahmed :waving_hand: - can you try running if you’re building on a dev shop:

shopify app dev --use-localhost

I’m wondering if there’s a configuration issue with the dev tunnel you might be using - when you run the app dev command to set up the app in the CLI, did it go through the initial set up questions (like which shop you’ll install it on, etc), or does it just abort the process right at the start there?

I think using localhost should resolve the issue if you wanted to try that, but if you do need to use a tunnel for development, I’m happy to keep digging into this for sure.

Hi @Alan_G,

Yes, I did set up the app and selected the partner store — not just once, but multiple times. However, I keep running into the same error each time.

I also tried running it on localhost, and it worked fine there. I even tested it with the ngrok tunnel, and while the app starts, the API calls aren’t going through — I’m getting a “trusted URL” error.

Ideally, I want to use the default trycloudflare tunnel that comes with Shopify apps, as that’s usually more seamless. Is there a way to ensure it’s being used correctly, or anything I should check to make sure it’s configured properly?

Thanks.

@Alan_G facing this same issue, it’s pretty annoying as I need my app to be hosted on cloudflare

Thanks for confirming @Ahsan_Ahmed and hi :waving_hand: @Ibrahim_Techie - thanks for reporting this as well.

Could you folks try running this command here when you launch app dev:

shopify app dev --verbose

If you can replicate the error in verbose mode and share the output, I can dig into this further with the team here and we’ll take a closer look.

Thanks for the support! @Alan_G I’ve pasted the logs below — please have a look.

Thanks @Ahsan_Ahmed - appreciate you trying that! I’ll do some more digging into this and loop back with you when I have some next steps/more info.
