Need some help here. I am not sure what is problem with my mapping.

I am using elasticsearch 5.3.1. I got an error from my logstash:

unsupported parameters: [properties : {arn={fields={keyword={ignore\_above=256, type=keyword}}, type=text}, userName={fields={keyword={ignore\_above=256, type=keyword}}, type=text}}]

the related template:

> ```
> "userIdentity": {
> "properties": {
> "arn": {
> "fields": {
> "keyword": {
> "ignore_above": 256,
> "type": "keyword"
> }
> },
> "type": "text"
> },
> "userName": {
> "fields": {
> "keyword": {
> "ignore_above": 256,
> "type": "keyword"
> }
> },
> "type": "text"
> }
> }
> }
> 
> ```
