My metafield / dynamic source shows blank or throws an error. Can you fix that?

Yes. A connected metafield can render blank, throw Liquid error: undefined, or refuse to bind as a dynamic source in the editor when the namespace.key is wrong, the metafield type does not match how it is used, or the reference {{ product.metafields.namespace.key %}} is malformed. We fix the namespace/key, correct the type handling, and repair the dynamic-source binding so the value shows on the storefront.
