Describe the bug
RevenueCatUI.PaywallError 0 won't trigger an error. There is no way to distinguish between this error and a successful paywall open. Not sure if it is intentional.

So for instance if you do:

import RevenueCatUI from 'react-native-purchases-ui';

 <RevenueCatUI.Paywall
      onDismiss={() => {
       //
      }}
      onPurchaseError={(error) => {
       //
      }}
      onRestoreError={(error) => {
      //
      }}
      options={{
        displayCloseButton: true,
        offering: {
          identifier: 'example',
          serverDescription: '',
          metadata: {},
          availablePackages: [],
          lifetime: null,
          annual: null,
          sixMonth: null,
          threeMonth: null,
          twoMonth: null,
          monthly: null,
          weekly: null,
        },
      }}
    />

The error handlers won't catch and it seems there is no way to capture that and handle. It is treated as a successful paywall open.

Maybe even simply fallbacking to the default offering would be better for this particular error at least?

Maybe a way to set either an overall default fallback offering when initializing RevCat (or let it fall back to the default offering set in the RevCat dashboard), or a way to at least be able to listen to this error happening, so we can react to it would be nice. 🙇
