How to bundle Cloud Logging entries by request?

I'm try to get Cloud Logging to bundle (i.e., group) log entries by request in Cloud Logs Explorer, similar to what node-js-logging-winston does on the Cloud Functions Node runtime: https://github.com/googleapis/nodejs-logging-winston#using-as-an-express-middleware It's also what App Engine does automatically.

There's general instructions in the following blog how to accomplish this using Python and Flask: https://medium.com/google-cloud/combining-correlated-log-lines-in-google-stackdriver-dd23284aeb29

Here's a screenshot of what it would look like in Logs Explorer.

Here's a script that is supposed to do this, but the entries are not grouping by request.


import argparse
import datetime
import time
import uuid

from google.cloud import logging


def _log_timestamp():
    return datetime.datetime.now(datetime.timezone.utc)


def _log_trace_id():
    return uuid.uuid4().hex


def _log_request_time(request_start_time):
    return "%.5fs" % (time.time() - request_start_time)


def run(project_id):
    request_start_time = time.time()
    trace_id = _log_trace_id()

    client = logging.Client(project=project_id)

    app_logger = client.logger('child')
    app_logger.log_struct(
        {"message": 'app log entry # 1'},
        severity='INFO',
        trace=f'projects/{project_id}/traces/{trace_id}',
        timestamp=_log_timestamp()
    )
    app_logger.log_struct(
        {"message": 'app log entry # 2'},
        severity='INFO',
        trace=f'projects/{project_id}/traces/{trace_id}',
        timestamp=_log_timestamp()
    )

    request_logger = client.logger('parent')
    request_logger.log_struct(
        {"message": 'TEXT'},
        severity='INFO',
        trace=f'projects/{project_id}/traces/{trace_id}',
        timestamp=_log_timestamp(),
        http_request=dict(
            request_method='GET',
            request_url='https://request.example.com/test-logging',
            status=200,
            user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko)'
                       ' Chrome/92.0.4515.107 Safari/537.36',
            response_size=15773,
            latency=_log_request_time(request_start_time),
            remote_ip='127.0.0.1',
            referer='https://referer.example.com/',
        )
    )


if __name__ == '__main__':
    parser = argparse.ArgumentParser(
        description=__doc__,
        formatter_class=argparse.RawDescriptionHelpFormatter
    )
    parser.add_argument('--project',
                        required=True,
                        help='Project ID')
    args = parser.parse_args()

    run(args.project)

And here is a screenshot of Logs Explorer showing the request was not bundled together:
