But it was not display in the list and below error was captured in logs:

Answer 1

This is possibly because of SolrCore connection issue. You can troubleshoot this by following the steps below

1. Navigate to the C:\inetpub\wwwroot\siteinstance.xConnect\App_Config\ConnectionStrings.config (sc901 is the name of the site)

   <add name="solrCore" connectionString="https://localhost:8983/solr/sc901_xdb" />

2. Check the if the code listed in the SolrCore exisits and accessible via solr dashboard.You can check this by navigating to https://localhost:8983/solr/#/ and also make sure C:(where ever the solr host files are located)\solr-6.6.2\server\solr contains the same 'sc901_xdb' folder.

3. If it does not exists, you can create xDB and xdb_rebuild cores by using the link https://doc.sitecore.net/developers/xp/xconnect/xconnect-search-indexer/rebuild-index/rebuild-solr-index.html#create-a-rebuild-core.

4. If exists, check to see if you get any additional solr connection errors in the log file of xConnect site and sitecore instance site also.
