Surely the real HEX from the log will be requested.
Try enabling full stack traces to see more details about the error.

Looks like you misconfigured something. Specifically Firebase configuration is missing.
Thank you very much Anton, in the process of upgrading to version 5.9 I forgot to configure WhatsApp notifications correctly.
Hi Cristian, If you got whatsapp working correctly you might reply here.
https://www.traccar.org/forums/topic/whatsapp-notifications-instead-of-telegram/#post-92297
actually the correct answer was that I had not configured push notifications properly (firebase).
But you can also have WhatsApp notifications in Traccar.
I recently upgraded to version 5.9 of Traccar and I have detected that I am getting the error
error - NullPointerException

I checked in the forum and found other similar cases but where you can detect the problem more easily, but in this case I do not know why the error occurs.
any suggestions?
