A brand new local XP0 developer install of Sitecore 9.1 continually throws the following errors in the xConnect logs:

2018-12-11 20:43:33.928 +08:00 [Error] Sitecore.XConnect.Operations.AddContactOperation: Sitecore.XConnect.Operations.EntityOperationException: Operation #0, AlreadyExists, Contact
2018-12-11 20:43:33.929 +08:00 [Error] Sitecore.XConnect.Operations.SetFacetOperation`1[Sitecore.XConnect.Facet]: Sitecore.XConnect.Operations.FacetOperationException: Operation #1, ReferenceNotFound, Contact, Classification

Sitecore XP website logs are clean and data is appearing in analytics. There is no custom code at all. Marketing definitions deployed, indexes rebuilt, but the error remains. Any suggestions ?

Thanks

This was caused by installing after a prior installation which had failed, without deleting the SOLR indexes. Removing SOLR indexes and reinstalling fixed the issue.

  • Which SOLR indexes did you have to remove and readd? – Koen Heye Jul 12 '19 at 13:08
  • I deleted and re-created all of them. – andyp Jul 15 '19 at 1:18

    For the someone who faces the same issue, I came across this error and was resolved by xDB index rebuild. – NutsAndBolts Aug 7 '19 at 4:01
