> When sending document updates to Solr, we occasionally see the following error:
> {noformat}
> java.lang.NullPointerException
> at org.apache.solr.client.solrj.impl.CloudSolrClient.requestWithRetryOnStaleState(CloudSolrClient.java:1182)
> at org.apache.solr.client.solrj.impl.CloudSolrClient.request(CloudSolrClient.java:1073)
> at org.apache.solr.client.solrj.SolrRequest.process(SolrRequest.java:160)
> at org.apache.solr.client.solrj.SolrClient.add(SolrClient.java:173)
> at org.apache.solr.client.solrj.SolrClient.add(SolrClient.java:138)
> at org.apache.solr.client.solrj.SolrClient.add(SolrClient.java:152)
> {noformat}
> Looking at the code, there is a lack of null check on requestedCollections around the for loop
> for (DocCollection ext : requestedCollections)
> which causes the error. Wrapping this loop with if(requestedCollections != null) would solve the problem.
