Sentry.init()
Sentry.init({
dsn: SENTRY_API_KEY
});Steps to Reproduce
- Build iOS app using npx react-native run-ios
Expected Result
No conversion errors logged in Xcode console.
Actual Result
JSON value '<null>' of type NSNull cannot be converted to NSDictionary
JSON value '<null>' of type NSNull cannot be converted to NSString
Reloading the app in the simulator will log them again:
JSON value '<null>' of type NSNull cannot be converted to NSDictionary
JSON value '<null>' of type NSNull cannot be converted to NSString
When removing Sentry.init the error logs are gone.
