In your code, the variable "data" is actually a list of instances of the field in the packet (each represented by a FieldInfo object). To get the values, you'll need to iterate the list:

for _,fieldinfo in pairs( data ) do
    print( fieldinfo.label, fieldinfo.value )
end

Woops, forgot to wrap data. Try this:

for _,fieldinfo in pairs({ data }) do

    print( fieldinfo.label, fieldinfo.value )

end

And to get the value in hex, you have to convert the UInt64 object to a string, and pass the result to tonumber().

    print(string.format("%X", tonumber( tostring(fieldinfo.value) ) ))
