    [ https://issues.apache.org/jira/browse/SOLR-8059?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15035117#comment-15035117 ] 

Mani commented on SOLR-8059:
----------------------------

In addition to the above this can be narrowed down to without looking at the source code *fl=id,score* & *debug=results* NPE is thrown. 

*Steps to reproduce*
./bin/solr start -e cloud #2 shards, 1 replica
./bin/solr status
./bin/post -c techproducts example/exampledocs/*.xml
{noformat}
curl "http://localhost:8983/solr/techproducts/select?q=*%3A*&wt=json&indent=true&debug=true&fl=id,score" => NPE thrown
curl "http://localhost:8983/solr/techproducts/select?q=*%3A*&wt=ruby&indent=true&debug=results&fl=id,score" => NPE thrown
{noformat}

Following curl examples works fine
curl "http://localhost:8983/solr/techproducts/select?q=*%3A*&wt=ruby&indent=true&debug=query&fl=id,score"
curl "http://localhost:8983/solr/techproducts/select?q=*%3A*&wt=ruby&indent=true&debug=timing&fl=id,score"
curl "http://localhost:8983/solr/techproducts/select?q=*%3A*&wt=ruby&indent=true&debug=track&fl=id,score"

> I can reproduce it everytime. Strange enough fl=*,score, or any other content field does not! I have seen this happening in Highlighter as well on the same code path. It makes little sense, how would fl influence that piece of code, the id is requested in fl afterall.
