Validator Errors - unable to dereference URI & invalid extra points

[noursaidi]

I encounter the following message when running the validator. (SNS1 is a proxy device bound to a gateway)

Processing device #1/9: SNS-1/event_pointset
Warning: Nashorn engine is planned to be removed from a future JDK release
Error validating message: fatal: unable to dereference URI "file:event_pointset_point.json#"
    level: "fatal"
    uri: "file:event_pointset_point.json#"
    exceptionMessage: "event_pointset_point.json (No such file or directory)"

java.lang.RuntimeException: Metadata validation failed: Extra points: play_sound,room_temp,sound_level,sound_volume

Two problems I think with this message are:

1. Regarding “Error validating message: fatal: unable to dereference URI "file:state_pointset_point.json#”, (which also appears for other files such as "file:event_pointset_point.json#"

These files exist (error while running on linux too)

nournew@macbook udmi % find  ~/udmi -name event_pointset_point.json
/Users/nournew/udmi/schema/event_pointset_point.json
nournew@macbook udmi % find  ~/udmi -name state_pointset_point.json
/Users/nournew/udmi/schema/state_pointset_point.json

2. The message reports "extra points" which I do not think are extra are extra described in metadata. Could there be a debug mode which prints the payload too to help identify what the message parsed is?

The pointset from the metadata in the local site model directory is:

…
"pointset": {
    "points": {
      "play_sound": {
        "units": "No-units",
        "ref": "MV28.Present_Value"
      },
      "room_temp": {
        "units": "Degrees-Celsius",
        "ref": "AI3.Present_Value"
      },
      "sound_level": {
        "units": "No-units",
        "ref": "AI17.Present_Value"
      },
      "sound_volume": {
        "units": "Percent",
        "ref": "AV30.Present_Value"
      }
    }
  }
…

Event from a subscription to udmi_target is the following. I can't see any other messages which are different.

{
	"version": 1,
	"timestamp": "2021-08-08T10:36:15.839346Z",
	"points": {
		"play_sound": {
			"present_value": 1.0
		},
		"room_temp": {
			"present_value": 20.82
		},
		"sound_level": {
			"present_value": 35.53
		},
		"sound_volume": {
			"present_value": 71.0
		}
	}
}

The version of the UDMI git repo I'm running is the current latest:

commit 37486e632919909ce7389c2d016212d39cf13eb2 (HEAD -> master, origin/master, origin/HEAD)

    Update MessageValidator to fail when validation fails

#174 fixes the problem with file paths

[grafnu]

Also, the last message of each type is written to a file already: e.g. more out/devices/AHU-1/event_pointset.json (from the UDMI directory)

[grafnu]

I fixed the one error (with file paths), but there's too much in this one issue to track everything -- so I'm going to close this (first item fixed), and if there's other separate issues they should be opened separately.
