Hi Do you have all fields either "stored" or "docValues"? In that case, /export would be the "correct" solution for you.
Have you tried the new export CLI command? https://solr.apache.org/guide/solr/latest/deployment-guide/solr-control-script-reference.html#exporting-documents-to-a-file > bin/solr export --url http://localhost:8983/solr/gettingstarted --limit -1 > --format json --compress --out myfile If you get the same exception there, pleas paste the full stack trace along with information on what Solr version you are on, so we can see if it is a know bug.
