Modelling a composite Time Series ID

I have deployed the Azure Industrial IoT Platform to my Azure subscription. When it provisions Time Series Insights it uses a composite key for the Time Series Id.

I am having a hard time determining the format of the "Time Series ID" when modelling the instance.

TSI Instance Configuration Error:

Error description:

> Unable to create instance(s): Error in 1/1 instances.   >Instance-1:
> Values in a single time series ID
> '["i=2256,uat0b626473b51aad434992c48deefc9bb8d03ae7f2,uat0b626473b51aad434992c48deefc9bb8d03ae7f2"]'
> must match the time series ID properties
> '[publisherId:String,dataSetWriterId:String,nodeId:String]' defined
> for the environment.

The documentation doesn't really show how it should be formatted. (For example, should it include commas, square brackets, etc.)

The Time Series Id is showing as (Empty) when I view it in the UI, so I don't get any hints there:

Here is the sample telemetry:

  {
    "NodeId": "http://microsoft.com/Opc/OpcPlc/#s=AlternatingBoolean",
    "EndpointUrl": "opc.tcp://10.1.8.5:51200/",
    "ApplicationUri": "urn:OpcPlc:410bf7b98fc2",
    "DisplayName": "AlternatingBoolean",
    "Timestamp": "2020-08-12T19:07:38.4355693Z",
    "Status": "Good",
    "Value": {
      "Value": false,
      "SourceTimestamp": "2020-08-12T19:07:38.1007812Z",
      "ServerTimestamp": "2020-08-12T19:07:38.1007828Z"
    },
    "SequenceNumber": 1319,
    "ExtensionFields": {
      "EndpointId": "uat0b626473b51aad434992c48deefc9bb8d03ae7f2",
      "PublisherId": "uat0b626473b51aad434992c48deefc9bb8d03ae7f2",
      "DataSetWriterId": "uat0b626473b51aad434992c48deefc9bb8d03ae7f2"
    }

Can you point me in the right direction?

thank you for your question. You have encountered a bug in our experience that we are working on fixing. Once fixed, we will update the documentation. Sorry about the inconvenience it caused. Meanwhile you can add an instance with a composite ID through API, by following the instructions here: https://learn.microsoft.com/en-us/rest/api/time-series-insights/dataaccessgen2/timeseriesinstances/executebatch#instancesbatchput

It should resolve your issue.
