@Liam-Shopify

when running the command, an error occurred.

I have theme extensions

extension file :

@xiuqing_zhao It’s possible this is network related - if you switch to a different internet network, do you still see this issue?

no,I failed to connect both using the local network and with a VPN ;

If you try to create an app without a theme app extension, (eg: checkout extension instead) are you seeing the same error?

If I hadn’t created theme app extension, this problem wouldn’t have occurred.

That does sound strange alright - the error type does seem related to network however, and I can’t replicate it myself. Is there any chance you could try using a mobile hotspot?

Could this be related to the country? I’m from China. But I used a VPN proxy;

It may be firewall related - I know there have been some issues with the CLI related to country limitations: [Bug]: Execute Shopify theme dev with error message: request to xxx.theme.json?xxx processing failed, reason: read ETIMEDOUT · Issue #3225 · Shopify/cli · GitHub

Let me give it a try.

But there is no problem for me to develop using Shopify CLI.

I believe it’s due to how theme/liquid files are handled using the CLI - so app specific commands will work as expected, but since theme app extensions involve using Google Cloud services, this can cause a network error.
