Issue with Marshmallow Module Not Being Found

Hi there,

First off, thank you for this guide for the Lambda set up! It was relatively easy to follow along and figure out :)

I have a persistent issue where I try to hit the api endpoint and get an internal server error. Digging through Cloudwatch I am posed with the following:

  | 2020-07-15T21:48:05.896-04:00 | deps loaded to tmp

I've tried everything I can think of to attempt to make sure Marshmallow is getting installed, but to no avail. Things I've tried:

  • Changing the version in ge-requirements.txt
    -- Forcing a version (2.2.0, 3.7.0, etc.)
    --No version specified
  • Reunning the build_layer.sh script with the above changes
  • Attempting to manually add marshmallow to the deps zip (this was more out of desperation, I figured it wouldn't work)

I've verified that Marshmallow is being installed when running the build script as well.

Additionally, I am getting an error when attempting to run the layer build script, I'm not sure if it could be related to the Marshmallow package not being found.

Running on Windows 10. Build script is run using cygwin and the remainder of the guide is completed using PyCharm and it's terminal included in the IDE.

Let me know if there's anything else I can include.

Thanks!
