That error message is from elasticsearch. You might get a better response if you move this to the elasticsearch forum.

While Elasticsearch \< 7 uses joda time for parsing, Elasticsearch \>= 7 uses java time. There are some subtle differences in parsing. In this examples, the month being all caps seems to be the problem. Trying this with `Aug` instead of `AUG` works for me.

Feel free to open a github issue explaining the different behaviour between ES 6 and 7.

Thanks!
