Push notifications to Traccar Manager

Hello, I am unable to make push notifications working.

this is my traccar.xml file:

I have added two keys for two different devices but non of them are working. When I try to test channels on the web I get this error:

MessageBodyReader not found for media type=text/plain;charset=utf-8, type=interface javax.json.JsonObject, genericType=interface javax.json.JsonObject. - MessageBodyProviderNotFoundException (... < NotificatorTraccar:106 < NotificationResource:96 < ... < OverrideFilter:50 < ...)

I am hosting my own server on raspberry PI and I am not a programmer. Can you please direct me to where can be a problem?

Thank you!

I have added two keys for two different device

This is definitely wrong. I'm also not sure how server keys are related to devices.

Yes, I can uderstand that. I have tried with one key only before and again and it is giving me the same error:

MessageBodyReader not found for media type=text/plain;charset=utf-8, type=interface javax.json.JsonObject, genericType=interface javax.json.JsonObject. - MessageBodyProviderNotFoundException (... < NotificatorTraccar:106 < NotificationResource:96 < ... < OverrideFilter:50 < ...)

Which key did you use? From what I can tell, both keys are wrong.

This one:

Is key copied from my mobile phone, under Account -> Account -> Atributes -> Notification Tokens

Thank you.

And why are you using this token? That's not the right token. You should probably carefully read the documentation first:

I am sorry. My bad. Thank you very much, it is now working! :)
