I'm trying to use a zip file created with zappa package instead of zappa deploy to match my CI/CD process.
AWS Lambda settings:
Runtime: Python 3.9
Handler: handler.lambda_handler
Architecture: x86_64
When I access the HTTP endpoint, it always returns null in the browser.
I created a Django project. It's a basic project, and you can check this project on the following GitHub repository. https://github.com/hongmingu/zappa1sample
I used the zappa package dev command to create a zip file and uploaded it to S3. Then, I set the S3 URL as the source in AWS Lambda.
Here's my zappa_settings.json file:
{ "dev": { "aws_region": "ap-northeast-2", "django_settings": "zappa1sample.settings", "project_name": "zappa1sample", "runtime": "python3.9", "s3_bucket": "lambda-saver12123" }, "production": { "aws_region": "ap-northeast-2", "django_settings": "zappa1sample.settings", "project_name": "zappa1sample", "runtime": "python3.9", "s3_bucket": "lambda-saver12123" } }
AWS CloudWatch logs are as follows:
INIT_START Runtime Version: python:3.9.v19 Runtime Version ARN: arn:aws:lambda:ap-northeast-2::runtime:e73d5f60c4282fb09ce24a6d3fe8997789616f3a53b903f4ed7c9132a58045f6

It keeps repeating like this, but the browser screen only shows the word null.
Just in case, I unzipped the zip file packaged with Zappa and found handler.lambda_handler as follows:
def lambda_handler(event, context): # pragma: no cover
return LambdaHandler.lambda_handler(event, context)
The returned LambdaHandler class can be found at the following address: https://github.com/Miserlou/Zappa/blob/master/zappa/handler.py
What should I do to solve this issue? Please help.
