    The tutorial you're following is quite old, so if you want follow the tutorial there are two options:

    1. the tutorial you're following misses the creation of Schema configuration in jcg collection. In this case you should fix your managed-schema file to jcg configuration taking care to add the following fields as suggested in the Tutorial, then reload the configuration (or restart Solr). At this point the "Indexing the Data" step should work correctly.
     <uniqueKey>id</uniqueKey>
     <!-- Fields added for books.csv load-->
     <field name="cat" type="text_general" indexed="true" stored="true"/>
     <field name="name" type="text_general" indexed="true" stored="true"/>
     <field name="price" type="tdouble" indexed="true" stored="true"/>
     <field name="inStock" type="boolean" indexed="true" stored="true"/>
     <field name="author" type="text_general" indexed="true" stored="true"/>
    
    1. You have correctly added schema and fields but not reloaded the configuration, but not reloaded the collection. So just reload the configuration (or restart Solr) and continue with the tutorial.

    On the other hand, if you're using an earlier version of Solr (6.4) I suggest to delete jcg collection and create it again:

    bin/solr delete -c jcg
    bin/solr create -c jcg -d ./server/solr/configsets/sample_techproducts_configs
