Index out of range in updateAssetTelemetry in the ADTClient

UA-CloudTwin/Applications/ADTClient.cs

Line 264 in 420384c

updateTwinData.AppendReplace("/OPCUANodeId", parts[1] + parts[3]);

When running locally the ADTClient gets an index out of range error on line 264. After inspecting the array, it seems that you have written the code for 1-based indexed arrays.

Are my assumption correct ? And if so, is there a particular reason for this ?

If not, is there anything wrong with the telemetryName that is passed into the function:
"opc.tcp://111.111.11.111:1111_11111111_somename;sensor-name;i=11111"

No metadata message for {publisherID}:{dataSetWriterId} received yet!

Hi,
We are working on a Twin for a factory with OPC UA devices, the data is flowing through a VM with IoT Edge and a OPC UA publisher to the IoT-Hub->UA-CloudTwin->ADT. We are getting the following information when we are running UA-CloudTwin:
"No metadata message for {publisherID}:{dataSetWriterId} received yet!" and the digital twins does not contain the metadata necessary to create relations and hierarchy.

The publisher looks like this with but with more nodes, different names and IP as well.

{ "EndpointUrl": "opc.tcp://111.111.11.111", "DataSetWriterGroup": "rh", "DataSetWriterId": 3, "OpcNodes": [ { "Id": "ns=1;s=/codesys/volatile/pdp/Multivac/R530/Advance", "HeartbeatIntervalTimespan": "00:01:00", "OpcSamplingInterval": 2000, "OpcPublishingInterval": 5000, "DataSetFieldId": "R530-Advance", "DisplayName": "R530-Advance" } }

In azure the message looks something like this:

[ { "MessageId": "4690", "MessageType": "ua-data", "PublisherId": "opc.tcp://111.111.11.111:rh", "DataSetWriterGroup": "rh", "Messages": [ { "DataSetWriterId": "3", "SequenceNumber": 4690, "MetaDataVersion": { "MajorVersion": 1, "MinorVersion": 0 }, "Timestamp": "2022-11-29T06:20:26.2187Z", "Payload": { "R530-Advance": { "Value": false, "SourceTimestamp": "2022-11-29T06:14:32.09145Z", "ServerTimestamp": "2022-11-29T06:14:32.3252Z" } } } ] } ]

Would it be possible to provide a valid example of a payload containing message data and metadata necessary to create a small hierarchy?
For example a factory with two machines with two sensors.
