Local Notification Error: `Unknown argument type 'UNNotificationRequest'`

[AlbertoMeQ]

Hello,

I'm experiencing this error:

Unknown argument type 'UNNotificationRequest' in method -[RNCPushNotificationIOS addNotificationRequest:]. Extend RCTConvert to support this type.

I'm using Xcode 13.1 and React-native 0.59.9. How can I fix it?

The error says to "Extend RCTConvert to support this type." but where would I do that?

How could I fix this?

Turns out that the files RCTConvert+Notification.h and RCTConvert+Notification.m were not included in the project file, so the definition couldn't be found.
