My Index: cls-docker-logs\*

Existing mapping in index cls-docker-logs-2023-01-18  
GET cls-docker-logs-2023-01-18/\_mapping  
"stack\_trace" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 256  
}  
}  
},  
Updated the mapping to:  
"stack\_trace" : {  
"type" : "text",  
"fields" : {  
"keyword" : {  
"type" : "keyword",  
"ignore\_above" : 2560000  
}  
}  
},  
Created a scripted field from where i basically want the value and want to perform some string manipulation  
return doc['stack\_trace.keyword'].value;

I don't see any value after i run this  
What I am doing wrong here?  
How to update the cls-docker-logs\* index pattern overall?
