System Specs

            <artifactId>elasticsearch</artifactId>
            <version>6.7.0</version>

Issue

I have a date field which uses the mapping below

 "thisIsDate": {
      "type": "date",
      "format": "strict_date_time"
    }

The field is set up like in my application

 @JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSX", shape = JsonFormat.Shape.STRING, timezone = "UTC")
    public Instant thisIsDate;

And the data I am inserting into that field looks like this.

1900-10-22T12:34:56.78Z

But I keep getting back

"reason":"failed to parse date field with format [basic_date_time]"

I have used the following formats in the mapping but none of them fix my problem

1. date_time 
2. basic_date_time 
3. strict_date_time
4. "yyyy-MM-dd'T'HH:mm:ss.SSSX"

Could someone point me in the right direction?

The issue is happening due to incompatible version of Elasticsearch server and Elasticsearch client.

As mentioned in every release there are some changed being introduced in the server which won't work if you don't upgrade your client version and that's the reason elasticsearch releases even client with every minor release like 7.4,7.5,7.6,7.7 if these could work without any issues then there was no need to do that.

This is a known issue and there are several StackOverflow posts related to various weird issues when Elasticsearch client doesn't match the server version.

Best and neat solution is to make sure you use the same version of both server and client and update both of them simultaneously to avoid these weird issues.
