non-unsigned-integral type given for backstory.Network.sent_bytes: int 103454713"

Hey there,

I have some issues with a custom parser, and it’s erroring out with 

panic encountered: non-unsigned-integral type given for backstory.Network.sent_bytes: int 103454713"

     if ![no_bytes] {
       mutate {
         replace => {
            "event1.idm.read_only_udm.network.received_bytes" => "%{srcbytes}"
            "event1.idm.read_only_udm.network.sent_bytes" => "%{dstbytes}"}
       }
       mutate {
        convert => {
            "event1.idm.read_only_udm.network.received_bytes" => "integer"
            "event1.idm.read_only_udm.network.sent_bytes" => "integer"}
        }
     }
  }

If I don’t do the convert, it errors out on “   “string 103454713”

Thank you in advance.
