Azure Cloud Integration sync not working

Hi all,

I am trying to set up a demo with The Things Stack (Community ed) integrated with Azure IoT Hub but am experiencing issues with the sync between TTS and Azure IoT Hub. I followed the setup guide in the documentation (Azure IoT Hub | The Things Stack for LoRaWAN).

Upon device creation in TTS Console, I see the device appear in the IoT hub as it should. But when I add a device in the IoT hub, it does not appear in TTS Console. (For this i also followed the guide). In the Azure Application Insights I see that there are errors coming from the SubmitEvents function: Exception while executing function: Functions.SubmitEvents The requested name is valid, but no data of the requested type was found.

What is this error and how can I resolve it?

Best regards,
Jan
