> I wanted to see the current behaviour of the export writer when it came to
> boolean fields and ran into this issue.
> Start solr: ./bin/solr start -e cloud -noprompt
> {code:java}
> ~/solr-7.4.0$ curl -v
> "http://localhost:8983/solr/gettingstarted/export/?q=*:*&sort=a_b%20desc&fl=id";
> * Trying ::1...
> * TCP_NODELAY set
> * Connected to localhost (::1) port 8983 (#0)
> > GET /solr/gettingstarted/export/?q=*:*&sort=a_b%20desc&fl=id HTTP/1.1
> > Host: localhost:8983
> > User-Agent: curl/7.54.0
> > Accept: */*
> >
> < HTTP/1.1 500 Server Error
> < Content-Type: application/octet-stream
> < Content-Length: 0
> <
> * Connection #0 to host localhost left intact{code}
>
> This basically comes back with no response, and unless you look at the server
> logs can't tell what the error is. Chrome displays the attached screenshot
> which is what confused me to start with.
> From the logs
