Hello everyone,
I got a NullPointer-Exception running a select-SearchHandler with a suggest
component on multiple shards (cloud mode).
It does work in the same configuration with a single shard (or non-cloud setup).
The suggest requestHandler does work in both setups.
Exception:

Here is my configoverlay.json (everything else is default data-driven)
{
"userProps":{"update.autoCreateFields":"false"},
"searchComponent":{"suggest":{
"name":"suggest",

"/suggest":{
"name":"/suggest",
"class":"solr.SearchHandler",
"defaults":{
"suggest":"true",
"suggest.dictionary":"mySuggester",
"suggest.count":5},
"components":["suggest"]}}}
Did I do something wrong with my configuration?
