Theme app extension error when testing the app

[ecomunpacked]

Hi everyone,

I'm developing a publish app, and trying to create a theme app extension to add my app to the theme editor. But I always face this issue when try run the app "To preview your extensions, make sure that development store preview is enabled in the Partner Dashboard"

I've already enabled the option.

But it still doesn't work.

Could you please advice?

Many thanks,

[RinaA]

Please tell me solution

It was fine before using Remix.

You better turn it OFF.

Then run the below commands

npm run build
npm run deploy

This will deploy all the extensions attached to your project.

Now go to your Theme Editor of your store and add your theme extension app as an App Block and save the theme.

This will show your extension ui in the theme of your store.
