PUT /ag2\_vehicle\_stats

Then, I got the following error msg:

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?

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

Yeah, it works now.
Thanks for your help, David!
