Web notifications showing as undefined

hi

trying to implement web notifications on my traccar server and when i do a test it shows up on notification area as undefined

i noticed there are some past issues but not clear for me if any is related with my scenario as I see web notifications should work straight foward after configured

here some screenshots

current version of traccar 5.12 running in a ubuntu server, i just updated from version 4.1 but notifications werent set before the upgrade

does anybody else experienced similar issue or have any idea what to be checked ?

The "undefined" could mean you have some non-standard notifications. You should check what you get through the WebSocket connection.

Got these lines from log I capture but don´t anything that could indicate an issue

Have you checked the WebSocket connection data as I suggested?

sorry for my lack of knowlodge but do i check that ?

Network tab in browser developer tools.

that helped thanks )

here the request i see

OK, there's no websocket on your screenshot. You have to open it before you load the page.

here what is received when button test is pushed

Looks like it's expected.

should I see test as description instead undefined ?

i see if enable email on the same notification, the email arrives with correct description, it only happens on notifications for the web gui

should I see test as description instead undefined ?

No, as I said, it's expected.

then what is wrong ?

Nothing.
