Hi all  
Here i am trying to define custom template for csv data  
here is my template

```auto
PUT _template/speedtest
{
"template": "speedtest*",
"settings": {
"number_of_shards": "6",
"number_of_replicas": "1"
},
"mappings": {
  "type1": {
    "_source": {
      "enabled": true
    },
"properties": {  
"@timestamp": { "type": "date" },
"DeviceVendor": { "index": true, "type": "keyword" },
"@version": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
"DeviceType": { "index": true, "type": "keyword" },
"DeviceModel": { "index": true, "type": "keyword" },
"EnDepth": { "index": true, "type": "keyword" },
"AlarmName": { "index": true, "type": "keyword" },
"AlarmCondition": { "index": true, "type": "keyword" },
"Severity": { "index": true, "type": "keyword" },
"Actionable": { "index": true, "type": "boolean" },
"Enrich": { "index": true, "type": "boolean" },
"CreatedBy": { "index": true, "type": "keyword" },
"CreatedOn": { "index": true, "type": "date" },
"UpdatedBy": { "index": true, "type": "keyword" },
"UpdatedOn": { "index": true, "type": "date" }
}
}
},
"aliases" : { "aemdev" : {} }
}

```

After loading template into ES i creates an index with disabling dynamicmapping

```auto
PUT speedtest1
{
 "index.mapper.dynamic": false
}

```

after that ingest data into index with logstash

```auto
input {
  file {
    path => "/home/sgpl/AEM_Sampledata.csv"
     sincedb_path => "/tmp/AEM_Sampledata.csv"
    start_position => "beginning"
  }
         }
filter {

 csv {
columns => ["DeviceVendor1","DeviceModel1","DeviceType1","EnDepth1","AlarmName1","AlarmCondition1","Severity1","Actionable1","Enrich1","CreatedBy1","CreatedOn1","UpdatedBy1","UpdatedOn1"]
separator => ","
 }

mutate {
    add_field => { "DeviceVendor" => "%{DeviceVendor1}" }
    add_field => { "DeviceModel" => "%{DeviceModel1}" }
    add_field => { "DeviceType" => "%{DeviceType1}" }
    add_field => { "EnDepth" => "%{EnDepth1}" }
    add_field => { "AlarmName" => "%{AlarmName1}" }
    add_field => { "AlarmCondition" => "%{AlarmCondition1}" }
    add_field => { "Severity" => "%{Severity1}" }
    add_field => { "Actionable" => "%{Actionable1}" }
    add_field => { "Enrich" => "%{Enrich1}" }
    add_field => { "CreatedBy" => "%{CreatedBy1}" }
    add_field => { "UpdatedBy1" => "%{UpdatedBy1}" }
    add_field => { "CreatedOn" => "%{@timestamp}" }
    add_field => { "UpdatedOn" => "%{@timestamp}" }
}

prune {
        whitelist_names => ["^DeviceVendor$","^DeviceModel$","^DeviceType$","^EnDepth$","^AlarmName$","^AlarmCondition$","^Severity$","^Actionable$","^Enrich$","^CreatedBy$","^CreatedOn$","^UpdatedBy$","^UpdatedOn$","^@timestamp$","^@version$"]
      }
         }
output {
elasticsearch {
hosts => ["http://192.168.1.74:9200"]
index => 'speedtest1'
}
stdout {codec => rubydebug }
}

```

During ingestion i got following warning

```auto

```

and after that when i search for that indexed data in kibana i am getting following error on discovery page of kibana

```auto
Saved "field" parameter is now invalid. Please select a new field.

OK
273s
Discover: "field" is a required parameter

```

Please help me in finding my mistake overhere

Thank You
