S3 Decorator Error: AttributeError: 'NoneType' object has no attribute 'logger' Traceback

[smt7174]

I got an error when trying to use s3 decorator.

My code is below. (This is nearly equal to sample code in
https://github.com/serverless-operations/jeffy)

# Using python-requirements plugin of Serverless Framework.
# Unzipping package because 'pythonRequirements.zip' parameter is set true in 
# Serverless Framework
# Probably, unzipping operation effects nothing. 
# (In case of rest_api decorator, no error raised.) 
try:
    import unzip_requirements
except ImportError:
    pass

from jeffy.framework import get_app
app = get_app()

@app.handlers.s3()
def handler(event, context):

    print(event['bucket_name'])
    print(event['key'])

# Instead of using print method, I tried to use app.logger.info method, but the same error raised. 
# app.logger.info({'bucket': event['bucket_name']})

And error is the below.

[ERROR] AttributeError: 'NoneType' object has no attribute 'logger' Traceback (most recent call last):   
  File "/tmp/sls-py-req/jeffy/handlers/s3.py", line 50, in wrapper self.app.logger.exception(e)

Additional information:
In case of executing the code below, no error raised.

try:
    import unzip_requirements
except ImportError:
    pass

import json
from jeffy.framework import get_app
app = get_app()

def handler(event, context):

    app.logger.info({'bucket': event['Records'][0]['s3']['bucket']['name']})

Thank you for your reporting 👍

S3 handler requires s3:GetObject permission. Maybe, your function does not allow s3:GetObject.
But in that case you should get another error message. We will continue to examine why it is.

And we haven't enough information about the required permissions. So we will fix it soon.
