# Exception while handling Sitecore ContentSearch IndexingFinishedEvent, index was not found
## Description

On your Sitecore content delivery server, in your Sitecore logs, you see many occurrences of this message:

```text
Heartbeat ERROR Exception while handling event Sitecore.ContentSearch.Events.IndexingFinishedEvent
Exception: System.ArgumentException
Message: Index my\_Index was not found
Source: Sitecore.ContentSearch
​
at Sitecore.ContentSearch.ContentSearchManager.GetIndex(String name)
at Sitecore.ContentSearch.Maintenance.EventHub.UpdateIndexTimestampDirectHandler(Object sender, EventArgs args)
at Sitecore.Events.Event.EventSubscribers.RaiseEvent(String eventName, Object\[\] parameters, EventResult result)
at Sitecore.Events.Event.RaiseEvent(String eventName, Object\[\] parameters)
at Sitecore.ContentSearch.Maintenance.EventHub.<Initialize>b\_\_b(IndexingFinishedEvent event)
at Sitecore.Eventing.EventProvider.RaiseEvent(Object event, Type eventType, EventContext context)
```

## Explanation

This is an error in the configuration of Sitecore itself.

The error message is caused because `<MY_INDEX>` is defined in the Content Authoring server configuration but not in the content delivery server.

## Resolution

The first thing to do is to find the `<MY_INDEX>` index on the Content Authoring Server.
To do so:

. On the Content Authoring Server, do a Sitecore showconfig (`\http://<INSTANCE_HOSTNAME>/sitecore/admin/showconfig.aspx`).
. Search for the index that's displayed in the Sitecore log (in this case, `<MY_INDEX>`).
. Determine in which configuration file the index is located.
. On the content delivery server, edit the related configuration file by adding the reference to the missing index.
