Hey @TKIPisalegacycipher

I'm seeing this fail in AWS Lambda... trying to debug but getting the following error message

This library requires Python 3.7 at minimum. Python versions 3.6 and below are end of life and end of support per the Python maintainers, and your interpreter version is 3.8.16 (default, Mar 28 2023, 11:04:35) \n[GCC 7.3.1 20180712 (Red Hat 7.3.1-15)]. Please consult the readme at your convenience: https://github.com/meraki/dashboard-api-python

Let me know if I can provide any additional data to debug

[TKIPisalegacycipher]

Hi @msheiny thanks for reporting this. Can you drop to a console in your Python environment and provide the output of this script?

import sys

print(f'sys.version_info[0] is {sys.version_info[0]}')
print(f'sys.version_info[1] is {sys.version_info[1]}')
print(f'sys.version_info is {sys.version_info}')
print(f'sys.version is {sys.version}')

For example, here's the output in my environment:

~#@❯ python                                                                                                      ❮  

I added a bunch of logging to my lambda

[msheiny]

I looked over your code, im kind of baffled why this is failing. The above was logging lines I added within the code. I can't poke into the AWS lambda environment shell directly.

[TKIPisalegacycipher]

I'm no AWS expert but based on this article I presume you're using a lambda layer containing the meraki package. It also looks like a lambda layer can run a different version of Python than the lambda itself.

For that reason I suspect a mismatch somewhere. But you may want to consult AWS support or an AWS expert for more guidance here. In any case, I don't see any sign that the package itself is malfunctioning, but I'm open to reasonable improvements on this relatively simple version check.

[msheiny]

Looks like I'm not using any layers 😕

I also thought Amazon dropped support for Python <= 3.6

Yeah, i'll keep digging. This is really weird.
