dragino lgt-92 with latest script: payload is not parsed

[indexample]

my dragino lgt-92 sends an uplink unconfirmed with this payload on port 2:

AAAAAAAAAAAPtmQ=

when parsing this with the lgt-92 latest decoder (v1.6.4) it doesnt pass the validator ("Payload input could not be validly parsed"). Also the mapper integration complains in the uplink integration response: "body": "{"error":"Invalid Device Latitude or Longitude Values for Lat: 0 Lng: 0"}",
