-------------------------------------------------------------
Solr 8.11.1 works correctly. The stated error is "Ping query caused exception:
no field name specified in query and no default specified via 'df' param"
Here is the ping handler definition that caused the exception. The lines I
added to fix the problem on this particular core are commented out here.
{code:xml}
<requestHandler name="/admin/ping" class="solr.PingRequestHandler">
<!-- relative paths are resolved against the data dir -->
<str name="healthcheckFile">server-enabled.txt</str>
<lst name="invariants">
<str name="qt">/select</str><!-- handler to delegate to -->
<!--
<str name="defType">edismax</str>
<str name="qf">body to subject cc from</str>
-->
<str name="q">mail</str>
<str name="rows">1</str>
</lst>
</requestHandler>
{code}
I had removed the config usually present in examples that would add a df field
to /select.

I haven't yet done any testing on a real release, just the compiled version I
am running. Here is the ping handler definition that caused the exception.

> A lot of the pages in the UI report permission errors even when the actual
> problem is some other exception. For this screenshot, I clicked first on the
> Overview, and then on Ping ... there was a misconfig in the ping handler
> where it was not declaring a default field, so the query generated an
> exception which is attached to the issue. I did not have a security.json
> file.

> I also saw this on other things besides Ping when I was clicking around the
> admin UI during a solr service restart. The version info showing where the
