-------------------------------------

             Summary: Unclear error message due to a typo
                 Key: SOLR-16698
                 URL: https://issues.apache.org/jira/browse/SOLR-16698
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: contrib - LTR
    Affects Versions: 9.1.1
            Reporter: ILARIA PETRETI


If we execute a PUT request with a typo in the "feature-store" endpoint (we write feature*s*-store with an additional {*}s{*}), we receive an unclear error message:

{{}}
{code:java}
curl -XPUT "http://localhost:8983/solr/books/schema/features-store" --data-binary "@features.json" -H "Content-type:application/json" { "responseHeader":{ "status":400, "QTime":9}, "error":{ "metadata":[ "error-class","org.apache.solr.common.SolrException", "root-error-class","org.apache.solr.common.SolrException"], "msg":"Expected Map to create a new ManagedResource but received a java.util.ArrayList", "code":400}, "error":{ "metadata":[ "error-class","org.apache.solr.common.SolrException", "root-error-class","org.apache.solr.common.SolrException"], "msg":"Expected Map to create a new ManagedResource but received a java.util.ArrayList", "code":400}}{code}
{{}}

The same happens with a typo in the "model-store" (we write model*s*-store with an additional {*}s{*}):

{{}}
{code:java}
curl -XPUT "http://localhost:8983/solr/books/schema/models-store" --data-binary "@model.json" -H "Content-type:application/json" { "responseHeader":{ "status":500, "QTime":1}, "error":{ "msg":"class org.apache.solr.ltr.model.LinearModel", "trace":"java.lang.ClassCastException: class org.apache.solr.ltr.model.LinearModel\n\tat java.base/java.lang.Class.asSubclass(Class.java:3924)\n\tat org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:533)\n\tat 
... org.eclipse.jetty.util.thread.QueuedThreadPool$Runner.run(QueuedThreadPool.java:1078)\n\tat java.base/java.lang.Thread.run(Thread.java:833)\n", "code":500}{code}
{{}}

These error messages could be improved with a clearer definition of the error.
