Actual behavior

After a theme app extension has been created (using npm run shopify app generate extension)
npm run dev throws the following errors:

Verbose output

See actual behaviour (verbose log exceeded character count - can provide if there's an email I can send it to?)

Reproduction steps

1. npm run dev on clean app template -- works fine
2. npm run shopify app generate extension
3. npm run dev -- throws error

Additional info - I'm using the 'start with remix' app template in JavaScript. The type of extension is a theme app extension.

I tried the alternate command 'npm run generate extension' on a fresh template - same error occurred.

Update - looks like this was a conflict with a global Shopify cli install. Resolved by creating a new user account on my pc and working with the cli as an app dependency only, as recommended by the docs.
