Coveo for Sitecore 4.1 (February 2019)

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 4.1 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 4.1 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:

  1. In a file explorer window, open the <SITECORE_INSTANCE_ROOT>\App_Config\Modules\Coveo folder.
  2. Create a sub-folder called Analytics. It must be called Analytics exactly to avoid issues during a future upgrade.
  3. 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
  4. Paste the files in the <SITECORE_INSTANCE_ROOT>\App_Config\Modules\Coveo\Analytics folder.
