Hello, I have recently got this problem with parsing date of this format '2022-08-02T9:00:00 AMZ'.

```auto
failed to parse field [Date] of type [date] in document with id 'uVxVd4cB4mQncJVwtSB8'. Preview of field's value: '2022-08-02T9:00:00 AMZ'")

```

Then, I tried to change mappings with format "yyyy-MM-dd'T'HH:mm:ss 'Z'", but got another error

```auto
Mapper for [Date] conflicts with existing mapper:\n\tCannot update parameter [format] from [strict_date_optional_time||epoch_millis] to [yyyy-MM-dd'T'HH:MM:SS 'Z']")

```
