IoT Hub to EventGrid DeviceStatus change notification fails with error

Question

IoT Hub to EventGrid DeviceStatus change notification fails with error

Sereena Kurunkadan 0

I’ve set up integration for DeviceConnectionStatus changes using Event Grid for the IoT Hub we’re using. However, I’ve noticed some errors occurring during the process.

Some of the errors observed include:

httpStatusCode=InternalServerError, errorType=UnexpectedError, errorMessage=An unexpected error has occurred. Please report the x-ms-request-id header value to our forums for assistance or raise a support ticket., errorMessage=Unable to create the items needed to communicate with the Event Hubs service
Another instance: errorCode=, httpStatusCode=InternalServerError, errorType=UnexpectedError, errorMessage=An unexpected error has occurred. Please report the x-ms-request-id header value to our forums for assistance or raise a support ticket.

I have the complete details captured from the AegDeliveryFailureLogs table in Log Analytics and can share them with you over chat if helpful.

Could you please guide me on how best to troubleshoot and resolve this issue? Support case model is changed from Microsoft where to raise ticket I need to upgrade to standard model which is 100 $ per month above my limits for now)

Hello @Sereena Kurunkadan ,

welcome to this moderated Azure community forum.

Better questions with more information lead to better answers from our community members.

Please provide information about the steps you have taken, the guide you follow, and where you receive the errors so fellow members can understand your question better.

Have you tried forwarding these connection messages to an eventhub instead (via custom routing)?

Hi Sereena Kurunkadan,

Looks like Event Grid is failing internally when trying to route events from IoT Hub using Event Hubs infrastructure.

This could be a transient issue. Ensure your downstream processing system has a retry mechanism for transient failures.

Make sure the IoT Hub has proper permissions to perform the actions.

Check if the IoT Hub or Event Grid Topic is approaching any limits.

Enable diagnostics logs to capture backend processing issues for both Event Grid and IOT Hub.

Kindly consider upvoting the comment if the information provided is helpful. This can assist other community members in resolving similar issues. If any other further queries - feel free to reach out!

@Sereena Kurunkadan Thanks for your patience on this and sharing the requested details.

Issue : IoT Hub to EventGrid DeviceStatus change notification fails with error

Root Cause:

I have reviewed the backend logs for the shared event grid resource "onesXXXstatus" over the past 2 days we don't see any delivery failures.

Also, based on the shared timestamp I have checked with internal team upon deeper investigation team has confirmed that this has happened due to a code regression and they had created a fix and deployed as well.

Please accept as Yes if the answer is helpful so that it can help others in the community.
