The error message you received indicates that there was an issue with mapping the region to a geographic location. In this case, the region is "southindia".
This error can occur if the region is not recognized by the system or if there is an issue with the service that is responsible for mapping the region to a geographic location.
To resolve this issue, you can try the following steps:
- Verify that the region you are using is valid and recognized by the system. You can check the list of available regions in the Azure documentation. (very unlikely, but still worth giving a try)
- Check if there are any known issues with the service that maps the region to a geographic location. You can check the Azure status page or the Azure support site for any known issues or outages.
- Try creating the analytics rule in a different region. If the issue persists, try creating the rule using a different browser or clearing your browser cache.
- If the issue still persists, you can contact Azure support for further assistance. They may be able to provide more information about the issue and help you resolve it.
