Date format issue MMM D, YYYY h:mm:ss A

[Rajashree_Gr]

I'm facing the org.elasticsearch.index.mapper.MapperParsingException: failed to parse [date] - exception while loading the data to elastic search.

The date format used is a date: MMM D, YYYY h:mm:ss A.
The date value which I'm trying to load is Jan 3, 2019 4:34:34 PM.

I' not sure what is wrong here. I feel date input is exactly matching the format. But it is still failing.
I also tried using date: default format but it is also giving the same exception.

Please consult https://www.joda.org/joda-time/apidocs/org/joda/time/format/DateTimeFormat.html, referred here: https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html#custom-date-formats

For example, you should be using a instead of A for the AM/PM

As i have AM/PM values in capital i used A instead a. When i verified this format in Kibana - date format pattern, it was giving me the date as expected. I will try it with 'a' instead of 'A' to see if it works.

I'm going through https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html#built-in-date-formats. I think we should use strict date format always.

It is mentioned that - ' For instance a date like 5/11/1 would be considered invalid and would need to be rewritten to 2005/11/01 to be accepted by the date parser.' I will try this option as well to see if it works.

I was able to format the date by referring to the website. I got the working date format YYYY-MM-DD'T'HH:mm:ss.SSS.

I'm trying to add the Zone name (like CST) to the above date format by adding z. But YYYY-MM-DD'T'HH:mm:ss.SSSz is not working and I tried many variations but none of them are working for me. I was able to get the zone offset by using 'Z' but not Zone name.
Is the date format with zone name is not supported in elastic search?
