Hey @anhtuan2810!
Please feel free to fill out another issue with more complete information.

I'm closing this for now.
Thanks!

I'm getting this same error from this morning:

Happens when starting dev server shopify app dev and I've tried logging out and in from CLI, and to update to the latest version.

I'm on windows. Yesterday it was working fine.

For the time being, I'm using WSL to start the dev server, which works. The difference I see from before is that now it asks for a store password when authenticating the CLI, which it didn't use to before, maybe it's related. Still doesn't work on windows.

Hey @anhtuan2810 @vincaslt! I've done some investigating, and in order to determine where the fix needs to live I need your help gathering data, as we unfortunately can't replicate this on our side. I also have a potential workaround in mind, but I need to validate something once I get the data.

What I need from you (using your own package manager):

1. Uninstall shopify cli

   npm uninstall -g @shopify/cli

2. Install this custom snapshot

   npm i -g @shopify/cli@0.0.0-snapshot-20241031232434

3. Run the command again with the verbose flag

   shopify app dev --verbose

4. Share the verbose logs by filling out the template that is linked here

You can also try this workaround - Please let me know if this works so that we can introduce a programatic fix if this occurs in the future

1) Ensure that you're accessing the right store shopify theme list --store=<YOUR_STORE>

2) Run the following command to delete the host theme attached to your theme app extension (this is safe and won't affect your extension - these host themes are designed to be ephemeral)

shopify theme delete -t=$(shopify theme list --name="App Ext. Host*" | grep -o '#[0-9]*' | tr -d '#')

3) Verify that the theme was deleted. You should NOT see any themes called App Ext. Host.

shopify theme list 

If you do see such theme, delete it using shopify theme delete -t=<THEME_ID>

4) Run app dev again.

5) Update me with your results here please!
