Unable to use scripted fields with Kibana 7.2

[tturpin (Tammy)]

We recently upgraded from Kibana 6.5.1 to 7.2. I'm having very strange behavior with my scripted fields. I'm unable to view any of my searches on the Discover tab. I get an error that states "1 of 161 shards failed", but when I go to my dashboard everything displays as expected.

I deleted my scripted fields and received the error below during the delete. When I went back to the Discover tab, my searches started working. I am not using the toLowerCase function in my scripted fields.

Version: 7.2.0
Build: 24337
Error: Uncaught TypeError: (filter || "").toLowerCase is not a function (https:{servername}/built_assets/dlls/vendors.bundle.dll.js.233) at window.onerror (https://{servername}/bundles/commons.bundle.js:3:1630366)

Any ideas?

Could you provide the script that you're using as well as a sample of what your data/scripted field looks like?

def statusStr = doc['mdc.responseHttpStatus.keyword'].value;
if(statusStr != null && statusStr != "")
{
def status = Integer.parseInt(statusStr);
if(status >= 200 && status < 300)
{
return "Success";
}
else
{
return "Failed";
}
}

It worked fine in 6.5.1.

I want to return Success if it was a successful http code and Failed if it was not. I'm using this for a metric visualization.

Has anyone else had issues with scripted fields in Kibana 7.2?
