I find the issue it was something on server side of main app, i clean all and now is fixed and the funtion device_token return correctly the string of token!Thank you @divyeshlakhotia
Now i will go for next step call the push_notifications.send(device_token,‘Title’,‘Body’,‘Logo’,‘Link’)
it can be possible to send something like this:
push_notifications.send(device_token,‘Title’,‘Body’,‘’,‘’) without link and logo ?
Thank you!
