I am using elasticsearch 7.10. On Friday night, one of the indices threw the error llegal_argument_exception at
node FNZgMx35SGBsn8a1rs0WKQ Field [event.ingested] of type [keyword] does not support custom formats
How do I solve this?
elasticsearch 7.10 is EOL and no longer supported. Please upgrade ASAP.
