Nil Map when unmarshalling Json

[victorddiniz]

On function JsonMessageToRecord, the msg.Value may be a JSON literal null. In that case, according to Go's documentation:

Unmarshal first handles the case of the JSON being the JSON literal null. In that case, Unmarshal sets the pointer to nil

Given that, jsonValue will be a nil map and you cannot write any value to nil map.

It would be better to handle any errors before writing any values to the map and also to check if the map is not nil, as JSON literal null is a valid input.
