I am using Coveo for Sitecore 4 450 build. Noticing this error only on few environments. I looked up there is no CleanUpIndexAfterRebuildException entry in the coveo configs. Any ideas on how I can troubleshoot this?

Job started: Index_Update_IndexName=Coveo_master_index|#Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Coveo.CloudPlatformClient.Exceptions.CleanUpIndexAfterRebuildException: An error occurred while querying documents to delete. ---> Coveo.Framework.Utils.Rest.HttpClientException: Failed to obtain resource located at 'http://devsite/coveo/rest?pipeline='.

With this error in the stack trace "The remote name could not be resolved: 'platform.cloud.coveo.com'","errorCode":"NameResolutionFailure", it looks like your Sitecore instance can't communicate with Coveo Cloud.

Have you tried accessing this URL directly from a browser in this same instance?

You should probably check if there are any errors in the Coveo Diagnostic Page, accessible from YOUR_SITECORE_INSTANCE/sitecore%20modules/Web/Coveo/Admin/CoveoDiagnosticPage.aspx

  • No errors in diagnostic page. I am able to access Coveo Cloud portal from the server.

  • What happens if you try to access http://devsite/coveo/rest?pipeline= ? Nov 29, 2016 at 20:00
  • I am seeing the json object with results coming back.

  • Do you still have this error? Since the CleanUpIndexAfterRebuildPerformer class calls the same endpoint as when you load /coveo/rest, we have to find the difference between the two environments. Is there a proxy/load balancer between your Sitecore instance and the Coveo Cloud endpoint..? Dec 5, 2016 at 19:31
  • This is not happening anymore. Not sure what was the problem earlier. Thanks for the suggestions.
