Error using .getUser().isBot()

Hello guys ! Until now, I was using this lines :

Member author = event.getMember();
if(!author.getUser().isBot()) {...}

But today, I have this error on the author.getUser().isBot() function :

[Fatal] [JDA]: java.lang.NullPointerException
at MainBot.onGuildMessageReceived(...)

I was on JDA 3.0.0 and seeing that problem I updated to 3.3.0 but the problem still here. Do you know why ? Can you help me ?

Thank a lot 😃

It could have been an webhook message, as those don’t have members

[DV8FromTheWorld]

This should instead be:

if (event.getUser().isBot() || event.getMessage().isWebhookMessage()) 
{...}
else
{
    Member author = event.getMember()
    ...
}

Webhook messages do not have Member objects.
