# Handler Coveosearchendpoint has a bad module Managedpipelinehandler in its module list
## Description

Your Coveo Hive search page in Sitecore either doesn't load or returns a 500 error.

When you browse the reverse proxy endpoint (`+https://<INSTANCE_HOSTNAME>/coveo/rest+` by default), you see the following error:

`Handler "CoveoSearchEndpoint" has a bad module "ManagedPipelineHandler" in its module list.`

## Explanation

The Sitecore instance running in Classic Pipeline mode can't load the Coveo components properly.
An integrated pipeline mode is needed.

## Resolution

. Open IIS Manager and look at the advanced settings for the app pool the Sitecore site is associated with.
. Change the Managed Pipeline mode to `Integrated`.
