Getting "ERROR update templates/product.json" error after adding product metafields

Hi!

One of our editors added some new product metafields and it looks like it broke this action - I'm not 100% sure this is the cause, but the error message seems to suggest it. This is the error I'm seeing:

What should we do in such case? Do I manually have to add these metafields in the store used by this action?

I managed to fix this error by manually adding all the missing product metafields to the development store used by this action.

What would be the best way to automate it? I don't think there's any webhook that is triggered whenever a new metafield definition is added via Shopify admin, so this sync would rather have to be part of CI flow, correct?
