Description

My cluster contains 3 Solr instances. I have a collection consisting of one shard with 2 replica's. So one node in the cluster does not have a replicate of the shard.

The following query works when I query one of the two replica nodes:

http://X.X.X.X:8080/solr/collection/select/?facet=true&facet.field=

{!ex%3Dfilters,filter1340+key%3Dfacet1340Values}string_months_month&facet=true&q=:

But when I query the node without the replica, I get;

{msg=Illegal character in query at index 78: http://X.X.X.X:8080/solr/collection/select/?facet=true&facet.field={!ex%3Dfilters,filter1340+key%3Dfacet1340Values}

string_months_month&facet=true&q=:,trace=java.lang.IllegalArgumentException

Without the facet.field attribute, it works fine on all the nodes.
Is this some kind of double escaping when proxying the request?
