error - Failed to get notificator V 5.7

Hi I updated to V 5.7 and is giving me this error

error - Failed to get notificator  - RuntimeException (NotificatorManager:75 < NotificationManager:110 < ... < *:107 < ... < *:106 < *:148 < ConnectionManager:247 < ...)

Also the devices disconnects all the time and it seems is after this error.

Please help

Probably some issue in your configuration.

I been trying to find documentation on this and I can not find anything. Like a sample file or something

Share your config. Specifically notificator.types parameter.

I only have this

<entry key='notificator.types'>web,mail,command</entry>

The error message indicates that you're not using the official version 5.7.

how I do to get the official version I downloaded from here ?

I downloaded traccar-linux-64-5.7.zip from https://www.traccar.org/download

I also Register in traccar and there us a key there that i do not find where to put it

The link is correct, but the error indicates that it's not what you're using on your server.

I've the same issue, but it only happens when a device exits a geofence, then disconnects from server and then reconect:

2023-05-29 19:26:03  INFO: [T97667981] error - Failed to get notificator  - RuntimeException (NotificatorManager:75 < NotificationManager:110 < ... < *:107 < ... < *:106 < *:148 < BaseEventHandler:40 < ...)
2023-05-29 19:26:03  INFO: [T97667981] disconnected
2023-05-29 19:26:04  INFO: [Ta44c51c9] connected

Also I've downloaded the raspberrypi version from traccar.org.

I've this in notificators line:

<entry key='notificator.types'>telegram,web,mail,sms</entry>

Test message works well.

And, if it help, I've a device model that send's ok geofences exits and doesn't disconnect: Sinotrack ST-901M. The other model that fails are Sinotrack waterproof ST-901 (that were sending geofences exits ok until 5.7).

Thanks

There's a notification configuration issue. Seems like you have an empty type.

Well, deleted unused web and sms notificators and still failing.

But what you say doesn't explain why some devices fails geofence exit notification with the RuntimeException and others doesn't.

Thanks in advance for your help.

Probably because you only assigned the notification to some devices.

I have finally fixed my problem with notifications.
I don't know how, but two rows of notifiers had been created in the database, one without data and the other with data. This last was used by the devices that were working.
However, on the web, when choosing a notifier for all devices, I could only choose the one that contained data in the database, but it worked for some devices and not for others.
Once the empty row was deleted and the notifications reconfigured, everything worked ok.
I hope this solution can help someone.
Thanks.
