I'm using Elasticsearch with ruby. I have a Date field that is a Datetime converted to "iso8601" on the format "2018-07-29T13:00:00Z" . the field is formatted as a date\_time\_no\_millis
attribute :starts\_at, Date, mapping: { format: "date\_time\_no\_millis" }
The problem is I'm getting date is too short, any suggestions
Elasticsearch::Transport::Transport::Errors::BadRequest: [400] {"error":{"root\_cause":[{"type":"mapper\_parsing\_exception","reason":"failed to parse [starts\_at]"}],"type":"mapper\_parsing\_exception","reason":"failed to parse [starts\_at]","caused\_by":{"type":"illegal\_argument\_exception","reason":"Invalid format: "2018-07-29" is too short"}},"status":400}

It's easier for us to help if you keep the question to one thread 🙂
