Watcher: getting painless script errors having null in email admin watches #43184
Description
Elasticsearch version (bin/elasticsearch --version): 7.1.1
Plugins installed: no
JVM version (java -version): On Elastic Cloud
OS version (uname -a if on a Unix-like system): On Elastic Cloud
Description of the problem including expected versus actual behavior:
I thought this has been fixed in #32923.
But I noticed a cluster running 7.1.1 is still getting the following error:
[instance-0000000006] failed to execute [script] transform for [h0rBJUPOSgeB-ZGRbrQ60A_elasticsearch_cluster_status_77a4d766-3da2-4b2b-92d9-451de304e9cf-2019-06-13T02:31:50.556Z]
