Issue with latest version of Azure Managed Grafana 11.6.3

Javier Huamani 60

We recently have upgraded all our Azure Managed Workspaces to version 11. A couple days ago we saw the update to version 11.6.3. However, now any time we attempt to create a Kusto Query variable in any Dashboard, we get the following error message. We cannot continue to develop new Dashboards with this existing issue:

After reviewing the ADX plugin repo, we determined that this issue should be resolved with the ADX plugin version 6.1.1. However, all our workspaces have version 6.1.0. Could we receive assistance in upgrading our plugin to the latest version?

Hello Javier Huamani,

To upgrade your Azure Managed Grafana workspace to the latest ADX plugin version (6.1.1) from version 6.1.0, follow these steps:

Steps for Upgrading the ADX Plugin in Azure Managed Grafana:

Log into the Azure Portal:

Ensure you have administrator or owner privileges for the Azure Managed Grafana workspace.

Navigate to Your Grafana Workspace:

Go to the Azure Portal.

In the search bar, type Grafana and select Azure Managed Grafana from the results.

Select the Grafana workspace you want to upgrade.

Go to the Plugins Section:

On the Grafana workspace blade, look for the Plugins option under the Configuration section.

Click on Plugins, which will show you a list of currently installed plugins (including Azure Data Explorer).

Find the Azure Data Explorer Plugin (ADX):

In the list of installed plugins, locate the Azure Data Explorer plugin.

If you are on version 6.1.0, it should show the installed version.

Upgrade the Plugin:

Look for an Upgrade button or an option to Update the plugin to version 6.1.1.

If the upgrade is not available via the portal interface, you can try to uninstall the plugin first, then reinstall the latest version.

Note: You may also check for any patching updates by navigating to Grafana Plugin Repository or Grafana Cloud.

Reinstall the Plugin (if necessary):

If an upgrade button isn't available directly:

Uninstall the existing plugin (v6.1.0).

Then, reinstall the plugin by searching for Azure Data Explorer (ADX) in the marketplace. Select Install for the latest available version (v6.1.1).

Restart the Grafana Workspace:

After the upgrade, restart your Azure Managed Grafana workspace to ensure that the changes take effect.

You can restart the workspace from the Overview section of the Azure Managed Grafana workspace.

Verify the Plugin Version:

After upgrading, go back to the Plugins section and ensure the version listed is now 6.1.1.

Test the Kusto Query Issue:

Test creating a Kusto Query variable on a new dashboard to see if the error is resolved with the updated version.

If the error no longer occurs, the issue should be fixed.

Because the ADX plugin is a core plugin of Azure Managed Grafana, we can't upgrade and/or remove the plugin ourselves. We require Azure assistance to upgrade our plugin to the latest version 6.1.1.

Hello Javier Huamani,

You're encountering a known compatibility issue between Grafana v11.x and the Azure Data Explorer (ADX) plugin—specifically when defining Kusto Query variables on dashboards.

Since upgrading to Grafana v11 (and now 11.6.3), attempts to create a variable via KQL result in this error:

TypeError: Cannot read properties of undefined (reading 'map')

This stems from either:

Undefined or malformed query results being passed into the variable control widget, or
A mismatch between the ADX plugin version and Grafana v11.x APIs

1.So, validate the KQL query

Please run your same query directly in the ADX Web UI and confirm it returns a well-formed table. If the result set is ever empty or missing columns, the plugin may break. Add a fallback like | take 1 or include essential columns explicitly.

2. Upgrade to the latest ADX plugin (v6.x+)

Azure Data Explorer Datasource plugin v6.0.1 (May 2025) includes bug fixes and Grafana v11 compatibility improvements Microsoft Learn GitHub.
In Azure Managed Grafana, ensure your workspace is using the newest plugin and reinstall it if needed.

3. Reinstall the plugin

Even if you're on the latest version, reinstalling can clear corruption or caching artifacts—per recommendations

4. Disable dashboard-level transformations

If transformations are applied to query results before variable processing, temporarily disable them to isolate the issue

5. Inspect browser developer console

More detailed errors often appear here if the plugin tries accessing undefined properties

And Ensure Grafana v11.6.3 is paired with ADX plugin v6 +or newer.

Reinstall the ADX plugin:
- In Azure portal, go to Managed Grafana workspace → Plugins → Azure Data Explorer → Uninstall and then reinstall.
Reboot your workspace if necessary (to refresh plugin metadata).
Try creating the variable again using a validated query (e.g. including | take 1).

Overall, the best fix is: upgrade to ADX plugin v6.+, reinstall, and validate your query.

If that doesn’t work, consider a panel-based variable or downgrade Grafana temporarily while awaiting plugin maintenance.
