Hi Team,
We are trying to send a email notification to a list of users in case change request is rejected.
On customization part we are adding some line of code in out of the box java class ChangeRequestReject.java.
Below is the sample test code where we have added few lines of code(In red) to send email. Build of the code is successful, when tested locally, we are getting NullPointerException because NotificationSenderService notificationSenderService variable is initialized to null and hence throws exception when method [this.notificationSenderService.sendNotification(notification) ] is called.
Can anyone please let me know if the approach is corect? If yes, what is the issue in code.
The BPMN file used for this is the out of the box DCR BPMN.
