Json payload ignored when a tag is not found #484
Description
For MQTT Ingress, when any one of the tags is not found in the device file, the entire payload gets dumped. shdr does not work in this fashion. You can send any tag in shdr and it will just get ignored. MQTT ingest should function like shdr and just ignore the one tag.
Tested with Agent v2.3.0.16
ex.
In the json payload below, if the tag "blah" is not found in the device file, none of the other tags get processed. The entire payload and all its tags gets dumped. This is not a format error, it's just that one of the tags does not exist.
{
"exec": "ACTIVE",
"blah": "BLAH",
"avail": "AVAILABLE"
}
