Painless script failing whenever you fetch a field from doc

Elastic Stack Kibana
1

Hi,
I am trying out ‘Painless’ scripts on Kibana (by creating scripted fields Index patterns has been renamed to data views. | Kibana Guide [8.11] | Elastic). My script runs just fine until I access a field from “doc” object. I immediately get following Warning on Kibana UI:

Warning

Courier Fetch: 1 of 2 shards failed.

For some reason, line 6 of my script cause the warning and no logs are displayed on UI. If I remove this line(along with braces), it works just fine:

String featureName="pendingApp";
String key="customerFeatures.0.featureId";

if(doc.containsKey(key))
{
if(doc[key]=='yes')
{
return "AA";
}
}
return "N/A";

On Kibana, following is how actually the logs appear (you can see the field 'customerFeatures.0.featureId' is available):

41%20AM
41%20AM1638×1200 155 KB

Do I need to enable something on Kibana, or change the indexing somehow?

I will really appreciate any help,

Thanks

Hello,

What are you trying to accomplish with the scripted field?
If you are looking for the customerFeatures.0.featureId field to have the value yes you need to use doc[key].value == "yes"
