NullPointerException when canceling payment session: RNGosellSdkReactNativeModule is null in sessionCancelled callback

[HumedMohammed]

When starting a payment session using RNGoSell.goSellSDK.startPayment and then canceling it (e.g., by pressing the back button in the Android payment activity), the app crashes with a NullPointerException. The error occurs because RNGosellSdkReactNativeModule (the React Native bridge module) is null when the native Android code attempts to invoke the onFailure callback during sessionCancelled.

This prevents proper handling of cancellation events and leads to app crashes instead of graceful failure callbacks.

Steps to Reproduce:

1. Initialize the Tap SDK with valid credentials using RNGoSell.goSellSDK.setInit(appCredentials).
2. Call RNGoSell.goSellSDK.startPayment(config, 0, callback) with a valid configuration
3. In the payment UI, Press Google pay press close button, then press cancel button or cancel the session.
4. Observe the crash with the attached stack trace.

Expected Behavior:

• The cancellation should trigger the provided callback (e.g., handleResult) with a "CANCELLED" status, without crashing the app.
• The module should be properly initialized and available for callback invocations.

Actual Behavior:

• App crashes with NullPointerException because RNGosellSdkReactNativeModule is null.
• Stack trace points to GoSellSdKDelegate.sessionCancelled failing to call onFailure.

RNGoSell.goSellSDK.startPayment(
tapPaymentConfiguration({ amount }),
0,
handleResult
);
