Hi,

Use Case: Have an Elastic Search template gdp\_es1 which has three fields of type integer,interger,string  
col1: integer, col2:integer, col3:string, there is a corresponding index that is created for this templates  
gdp\_es1\_2018.03.01, when I try to update the template by adding another field (string) i am seeing the  
following exception,

"message": "Unable to update mapping for event type: gdp\_es1 due to: {"root\_cause":[  
{"type":"not\_x\_content\_exception","reason":"not\_x\_content\_exception: Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"}

the template gdp\_es1 has the new column added, but when I post data to the existing index gdp\_es1\_2018.03.01, it is ignoring the newly added column .

Is there no way to update an existing template with data (index) with a new column ?

Thanks,

Kasi
