The following warning occurs:

/home/sasaki/workspace/orcas_proj/venv/lib/python3.12/site-packages/logstash/formatter.py:73: DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.fromtimestamp(timestamp, datetime.UTC).
  tstamp = datetime.utcfromtimestamp(time)

Modify the format_timestamp method around line 73 of logstash/formatter.py as follows:

• Before the fix

    @classmethod
    def format_timestamp(cls, time):
        tstamp = datetime.utcfromtimestamp(time)
        return tstamp.strftime("%Y-%m-%dT%H:%M:%S") + ".%03d" % (tstamp.microsecond / 1000) + "Z"

• After correction (sample)

    @classmethod
    def format_timestamp(cls, time):
        from datetime import datetime, timezone  # <-Please write at the beginning of the line
        tstamp = datetime.fromtimestamp(time, tz=timezone.utc)
        return tstamp.strftime("%Y-%m-%dT%H:%M:%S") + ".%03d" % (tstamp.microsecond / 1000) + "Z"
