buySubscription returning E_UNKNOWN on iOS

Version of react-native-iap

0.3.10

Platforms you faced the error (IOS or Android or both?)

iOS

Expected behavior

A subscription purchase receipt is returned

Actual behavior

‘E_UNKNOWN’, ‘An unknown or unexpected error has occured. Please try again later.’

I’ve followed the setup instructions and am able to call getSubscriptions() and get back a valid subscription product.

When I call buySubscription(myValidProductId) I get back the unknown error noted above. Neither my app, nor the in-app purchase have been reviewed or approved as of yet, I’m still in development and testing phase. Should I be able to test actually purchasing a subscription in this way?

This has been tried both at the simulator and with app installed to my device.
