Getting NPE When using NotificationListener

[Rajagopal_Bojanapall]

Hello
I am using the code snippet mentioned here. Getting NPE when I called

member.getJoined()

I checked member is not null. Not sure what's the error. Printing the stacktrace. First 3 lines are my logging statements

Hi Raj.

I will see if we can get someone on the developer engagement to take a look at this.

Thanks,

Hi Raj,

I've been looking into this problem.

It appears that there is a bug in the notification service and for every membership event, two messages are sent in quick succession. One contains the joined boolean, the other doesn't.
The resulting exception from calling member.getJoined() on the message without the joined boolean is handled by the notification handler and logged using the default logger. It can safely be ignored.

I have reported this issue to the relevant team and they will work to resolve it.

Thanks for reporting,
Ronan
