# Send Analytics to Sitecore rendering not working


[.version.c4sc.c4sc-issue-resolved.5-0-239-2.February-26&-2019]
[Issue resolved](https://docs.coveo.com/en/2764#release-notes)


## Symptoms

When using the `Send Analytics to Sitecore` rendering in a Coveo-powered search page, you get the following error message on a `searchFromLink` event:

```text
Server Error in '/' Application.
Precondition failed: The parameter 'p_EventData' must not be null
Parameter name: p_EventData
Description: An unhandled exception occurred.
Exception Details: System.ArgumentNullException: Precondition failed: The parameter 'p_EventData' must not be null

Coveo.Analytics.xDB.Processors.HandleSitecoreSearchEventProcessor.Process(CoveoAnalyticsPipelineArgs p_Args) +333
```

## Cause

A `Coveo.Analytics.xDB.config` patch command isn't applied because configuration files aren't loaded in the proper order.

## Resolution

The issue has been corrected in the February 2019 version of Coveo for Sitecore 5 by moving the `Coveo.Analytics.xDB.config` file into a new `Analytics` sub-folder.

### Workaround

If you don't want to upgrade to the February 2019 version of Coveo for Sitecore 5 right now, you can perform the following steps to have the `Coveo.Analytics.xDB.config` file load at the right moment in the configuration file loading sequence:

. In a file explorer window, open the `<SITECORE_INSTANCE_ROOT>\App_Config\Modules\Coveo` folder.

. Create a sub-folder called `Analytics`.
It **must** be called `Analytics` **exactly** to avoid issues during a future upgrade.

. Select and cut the following files from the `<SITECORE_INSTANCE_ROOT>\App_Config\Modules\Coveo` folder:

** `Coveo.Analytics.XConnect.config.disabled`

** `Coveo.Analytics.xDB.config`

. Paste the files in the `<SITECORE_INSTANCE_ROOT>\App_Config\Modules\Coveo\Analytics` folder.
