Mapper parsing exception: Root mapping definition has unsupported parameters

[vernal]

PUT /ag2_vehicle_stats
{
"settings": {
"number_of_shards": 1
},
"mappings": {
"doc": {
"properties": {
"vin": {
"type": "keyword"
},
"error_reported": {
"type": "integer"
},
"num_records": {
"type": "integer"
},
"start_time": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss"
},
"end_time": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss"
},
"num_days": {
"type": "integer"
}
}
}
}
}

Then, I got the following error msg:
{
"error" : {
"root_cause" : [
{
"type" : "mapper_parsing_exception",
"reason" : "Root mapping definition has unsupported parameters: [doc : {properties={odo_index={type=integer}, battery_usage_high={type=integer}, daily_fuel_dist_p99={type=double}, num_records={type=integer}, new_seg_battery_drive_energy_capacity_in_kwh={type=double}, cell_volt_diff_drive_mean_now={type=double}, city_last_day={type=keyword}, battery_life_in_days={type=integer}, total_distance_on_battery={type=integer}, daily_batt_dist_p99={type=double}, daily_charge_energy_avg_in_kwh={type=double}, num_days={type=integer}}}]"
}
],

}
},
"status" : 400
}

What's wrong here?

I have changed "doc" to "_doc" and got new error as below:

The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true

Remove it entirely.

Thank you for the help David. It solved my problem.

Now another issue here:

I tried to put the command in python code to automate the process:
curl -H Content-Type:application/json --user admin:dev -XPUT localhost:9200/ag2_vehicle_stats-2020-03-23 -d @/home/elk-daily-updates/ag2_vehicle_stats.json

However, I got the following error msg:
"took" : 59303,
"errors" : true,
"items" : [
{
"index" : {
"_index" : "ag2_vehicle_stats-2020-03-23",
"_type" : "doc",
"_id" : "Nz0aHnEBZhYEtxZotiMK",
"status" : 400,
"error" : {
"type" : "illegal_argument_exception",
"reason" : "Rejecting mapping update to [ag2_vehicle_stats-2020-03-23] as the final mapping would have more than 1 type: [_doc, doc]"
}
}
}

What is wrong with the command above?

[dadoonet (David Pilato)]

.

Most likely your json file is using doc instead of _doc as the type name.

Yeah, it works now.

Thanks for your help, David!
