Date Joda parse does not work

Hi, I am trying to parse date to field @timestamp. My timestamp looks like below:

"Timestamp" : "11/20/2020 3:32:01 PM"

I tried:

date {
match => [ "Timestamp", "MM/dd/yyyy HH:mm:ss a" ]
remove_field => ["Timestamp"]

... or "MM/dd/yyyy KK:mm:ss a" or "MM/dd/yyyy KK:mm:ss aa" or ""MM/dd/yyyy hh:mm:ss a"...

Nothing work, log is not in Kibana or _dateparsefailure.

Would you know the solution? Thanks a lot!!

date { match => [ "Timestamp", "MM/dd/yyyy hh:mm:ss a" ] remove_field => ["Timestamp"] }

works for me

"@timestamp" => 2020-11-20T20:32:01.000Z

Do not use HH, since it will ignore the AM/PM if you tell it you have an hour in the range 0-23.

If the event is not visible in kibana check in elasticsearch directly. If it is not in elasticsearch then your problem is unrelated to the date filter.
