An Azure IoT Central App dashboard widget sometimes fails while others seem unaffected

Anonymous

We have a dashboard with various widgets referencing the same data in different time frames/ formats/ groupings etc.. Sometimes one of these widgets will fail with "Error code: 500.011.999.999 / cjke32l5zh.28" while the rest of them - which often reference the same telemetry - remain unaffected. Any idea what could be causing this? is this just transient error? Thanks.

Hello @LeelaRajeshSayana-MSFT I appreciate your response. It's just an event history component tracking roughly 15 events across roughly 8 devices. Upon switching the component type to an event chart it works fine. deleting and rebuilding yields the same error as well as reducing the events and devices the component is reporting. It seems to be an error specific to the event history type component.

Hi @Anonymous Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

The error code 500.011.999.999 / cjke32l5zh.28 is a generic error code that indicates that an internal server error has occurred in Azure IoT Central. This error code does not provide any specific information about the cause of the error. Can you share more details on how you have configured the dashboard and any grouping or aggregation functions you might have added to the dashboard tile?

Hello @LeelaRajeshSayana-MSFT and thanks for your response and welcome.

It's just an Event history chart view showing event history for roughly 15 events from about 8 devices. It had been working but suddenly stopped without any changes. Same result after deleting and rebuilding. Changing the visualization type to Event Chart using the exact same data works fine though. Reducing the the events to 2 and the devices to 2 has no effect - it very much feels like event history data component is specifically affected.
