Getting error while indexing


I installed coveo for sitecore on a sitecore 7.5 but whenever I try to index I get the error bellow.


Sitecore.NET 7.5 (rev. 141003)

CES: 7.0 7433

Search API: 8.0.457

Coveo for sitecore: 75 3.0 1081

The diagnostics page show that all services are up and running.

Any ideas on what could be wrong here?


Job started: IndexUpdateIndexName=sitecoremasterindex|#Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: Precondition failed: The parameter 'pParameterValue' must not be an empty string Parameter name: pParameterValue

The error is pretty general, but one thing I see is that your Coveo Back-End (Coveo Enterprise Search) is outdated compared to your Coveo for Sitecore. So simply upgrade your Coveo back end instance:

Simon is right, a change in the Admin Service, delivered with the CES release of June (7711), is required when upgrading Coveo for Sitecore, otherwise creating this particular issue. 7433 is the February release.

Yes this is a version issue :)
