Method Call in handleCommand

[JohannesR]

Hi Community again its me ;)

I want to call a method in my handleCommand method in the Handler class. but I always get a TimeoutException.

Even if the method is empty, is there a problem with calling methods in the handleCommand?

Hi Johannes,

There is a timeout of 5 seconds on these calls - but this timeout only means that the ERROR is logged to highlight that there seems to be a performance issue in your code. It should be nonetheless further executed, even if it takes longer than 5 seconds.

Even if the method is empty,

Are you sure? If the method returns immediately (and you do not cause it to stop with the debugger), this message should definitely not appear.

Regards,

Kai
