I am trying out the Azure Digital Twins solution. In the Time Series visualization step, I am getting an error while creating the endpoints.

https://learn.microsoft.com/en-us/azure/digital-twins/tutorial-facilities-analyze

Trying to create the endpoint as given in section "Create an endpoint for the event hub" is giving error:

Response Status: 400, BadRequest , {"error":{"code":"400.600.000.000","message":"Attempting to provision 'EventHub' endpoint resulted in exception 'Put token failed. status-code: 404, status-description: The messaging entity 'sb://v...

Any pointers to fix this? Thanks in advance.

Without seeing the request body its tricky to troubleshoot definitively. However, the first go-to troubleshooting tip would be does your endpoint contain the EntityPath at the end of the connection string? EntityPath is not typically added by default when copying a connection string from the portal.

Endpoint=sb://nameOfYourEventHubNamespace.servicebus.windows.net/;SharedAccessKeyName=ManageSend;SharedAccessKey=yourShareAccessKey1GUID;EntityPath=nameOfYourEventHub

  • Thanks for looking into this, Tyler. The EntityPath is present for both primary as well as secondary keys. Ex: ``` Endpoint=sb://vaidya-digital-twins-event-hubs-namespace.servicebus.windows.net/;SharedAccessKeyName=ManageSend;SharedAccessKey=;EntityPath=vaidya-digital-twins-event-hub. ``` Unfortunately the response body string is truncated and so I am not able to figure out the exact issue. – Vaidya Siva Feb 14 '19 at 08:21
  • Next you should ensure that the Path is set to the name of the `EventHub` created within your `EventHubNamespace` not the name of the Namespace. The error you are seeing is due to a validation that the EventHub you are passing DigitalTwins actually exists (protection from typos, though still in preview and rather rough). Where are you seeing the truncated response body? – Tyler Angell Feb 15 '19 at 01:27
  • Thanks, Tyler. Verified that the entity path is indeed set to event-hub ("vaidya-digital-twins-event-hub") and not the namespace (which has the namespace appended to it). The truncated response body is the console output on executing the "dotnet run CreateEndpoints" command. – Vaidya Siva Feb 15 '19 at 05:16
  • Oh! There is a typo in the config instructions on the page you linked. The `path` variable in the `actions\createEndpoints.yaml` config should read `Name_of_your_Event_Hub` not the namespace. This is the same value as your `EntityPath`. – Tyler Angell Feb 15 '19 at 18:31
