Mikhail Khludnev commented on SOLR-13509:
-----------------------------------------
Right, this was introduced by SOLR-9882. I suppose it's worth to randomly omit
header at {{CloudExitableDirectoryReaderTest.testCreepThenBite.}} I'm not sure
whether it safe (but it should) always request header for subordinate requests.
Shouldn't \{{FacetModule.handleResponses}} just bypass if response's header is
absent?

> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Facet Module
> Affects Versions: 8.1.1
> Environment: Solr 8.1.1 downloaded tar gz, started in cloud mode:
> {code:java}
> bin/solr start -e cloud -noprompt
> bin/solr create -c techproducts -s 2 -rf 2 -d
> server/solr/configsets/sample_techproducts_configs/conf -n
> sample_techproducts_configs
> bin/post -c techproducts example/exampledocs/*.xml{code}

> The error exists in Solr 8.1.1 and didn't occur in Solr 8.0 and 7.x.
> Running this simple JSON Facet against the techproducts example (in cloud
> mode) succeeds as expected:
> {code:java}
> curl http://localhost:8983/solr/techproducts/select -d '
> q=*:*&
> omitHeader=false&
> json.facet={
> "max_price" : "max(price)"
> }{code}
> But as soon you omit Headers it results in a NullPointerException (which
> didn't happen in earlier Solr versions):
> {code:java}
> curl http://localhost:8983/solr/techproducts/select -d '
> q=*:*&
> omitHeader=true&
> json.facet={
> "max_price" : "max(price)"
> }'
> {code}
> Exception:
