**Your software**  
My Mautic version is: 3.2.1  
My PHP version is: 7.4  
My Database type and version is: mysql 7.4

**Your problem**  
I am trying to send pushes through Mautic to my mobile. In the docs it states to make an entry using

> ```
> /notification/appcallback
> 
> ```

I am getting

> {  
> “contact\_id”: “4187”,  
> “stat\_recorded”: false,  
> “push\_id\_recorded”: true  
> }

and a contact is getting created. But when I try to send push to that contact, it gives me an error

> This event encountered an error during the last attempt to process

These errors are showing in the log:
