We are getting this crash. I checked native android files for quickblox-react-native-sdk and figure out that addMessageStatusListener is fired when connect (inside ChatModule.java) method returns success.
Inside addMessageStatusListener method we are using QBMessageStatusesManager instance. We are getting this instance as null.
This can be null only if this.connection (Inside QBChatServices.class) is not connected or not authenticated. We are connecting and authenticating user inside login method in QBChatService.class. May be either connection is not successful or user is not authenticated and "connect" method returns success and we are getting crash. Please help in resolving this crash.
