I am getting stuck with both a custom parser, as well as parser extension, on this error

generic::unknown: invalid event 0: LOG_PARSING_GENERATED_INVALID_EVENT: "generic::invalid_argument: *events_go_proto.Event_Webproxy: invalid target device: device is empty"

I already have a lot of the UDM mapped out, which am I missing?

Solved already, I had an error in my code whereby target.ip was not populated.
