Ingestion doc to index template

[accateo (accat)]

Hi,
I've created a index template in Kibana:

{
      "properties": {
        "date": {
          "type": "date"
        },
        "formatDate": {
          "type": "text"
        },
        "temp": {
          "type": "long"
        },
        "busErr": {
          "type": "long"
        },
        "deviceId": {
          "type": "text"
        },
        "version": {
          "type": "double"
        },
        "uptime": {
          "type": "double"
        },
        "avgLoad": {
          "type": "long"
        },
        "diskFree": {
          "type": "long"
        }
      }
}

and I tried to ingest doc via NodeJS Application in this way:

var new_j = {"deviceId" : "XXX", "version": version, "uptime" : uptime, "busErr" : busErr, "avgLoad" : avgLoad, "temp" : temp, "diskFree" : diskFree, "formatDate" : formatDate(), "date" : new Date() };

client.index({
                             index: 'device_data_bridgenuzoo',
                             type: 'telemetry',
                             body: new_j
                        }), (err, resp, status) => {}

but I have this error:

UnhandledPromiseRejectionWarning: ResponseError: illegal_argument_exception
      at onBody (/home/rob/elasticData/node_modules/@elastic/elasticsearch/lib/Transport.js:333:23)

Any idea? If I don't use the template, it works all without problem.
Thanks

When you don't use template, what mapping is created when you index this document? Have you compared it with your template and noticed any difference?

Best,
Oleg

Yes, I compared.

With a different index name:

{
  "mappings": {
    "telemetry": {
      "properties": {
        "avgLoad": {
          "type": "long"
        },
        "busErr": {
          "type": "long"
        },
        "date": {
          "type": "date"
        },
        "deviceId": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "diskFree": {
          "type": "long"
        },
        "formatDate": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "temp": {
          "type": "long"
        },
        "uptime": {
          "type": "long"
        },
        "version": {
          "type": "float"
        }
      }
    }
  }
}
