Sitecore EXM

Recently I have set up Sitecore 9.1 (scaled) for our UAT environment. While I was browsing the experience profile from the launchpad I was getting an error and no-data were displaying in the dashboard.

And in the CM log I found the following:

I searched in the internet and found that a lot of people saw this kind of error. While I compile their suggestions I found the followings:

  • xConnect certificate issue and need to check that root have duplicate certificates or not.
  • Ensure Newtonsoft.Json.dll version is the same as vanilla Sitecore package.
  • CM server could miss a connection string to xconnect.search.
  • Check xConnect logs, thumbprint, windows service logs, xConnect thumbprint details in app_config and app settings file.
  • Rebuild the xDB index in Solr.

I tried all the above and the following as well but there is nothing in the xConnect log or no issue with the certificate.

  • Ensured that the xConnect service is accessible from the Sitecore instance.
  • Ensured that the SOLR server used for xDB indexes is running and accessible from xConnect instances.
  • Ensured that the Contacts collection of the Shard databases is populated with new contacts.

Then I tried to create a contact list from the List Manager and I got another error. In the log I found the following:

After seeing the error message that models conflict and XConnectModel doesn’t have a remote version I realize the error could be related to xConnect model. Then I found our custom xConnect model is not in the “App_Data/Models” directory. Once I put it there data starts coming in the experience profile.

It looks like the error we get is not all the time referring to the correct issue. It is worth checking its surroundings.

Thanks
