@MAMIDI Anjali Thanks for reaching out.
It looks like you are using the When a resource event occurs triggers (event grid connector) and as per the error message under the setting you can see the Split On property enabled for your trigger so that means per item in your selected array it will have the district tracking it. If you have disabled it then all the events will process by the same instance for a particular time.
If there is only the single json object and not the array then you can disable it.
