Crash in RNGooglePayModule on Firebase - onActivityResult NullPointerException

[SanjayVrize]

Hello Team,

I’m experiencing a crash in the RNGooglePayModule at com.busfor.RNGooglePayModule$1.onActivityResult, specifically related to the requestPaymentPromise object being null. The crash occurs when the onActivityResult method is triggered, and it tries to access requestPaymentPromise.reject(), resulting in a NullPointerException. This appears to be happening when the Google Pay activity result returns RESULT_CANCELED or RESULT_ERROR, and requestPaymentPromise hasn’t been set.

Caused by java.lang.NullPointerException: Attempt to invoke interface method 'void com.facebook.react.bridge.Promise.reject(java.lang.String, java.lang.String)' on a null object reference
at com.busfor.RNGooglePayModule$1.onActivityResult(RNGooglePayModule.java:xx)

Proposed Solution: To address this, I would suggest adding a null check for requestPaymentPromise within the onActivityResult method to avoid calling .reject() on a null reference. However, since this would require modifying the library code, it introduces maintenance risks and may not be ideal without your review.

Request: Could you please look into this issue? It would be great if a fix could be implemented, or if guidance could be provided on a recommended approach to handle this.
