Python Layer Image Failing: "Unable to import module 'lambda_function': cannot import name '_imaging' from 'PIL'"

I'm simply trying to be able to use PIL in my Python 3.8 Lambda.

I'm trying the following steps:

1. Based on this repo: https://github.com/hidekuma/lambda-layers-for-python-runtime

cd /mydir 
git clone https://github.com/hidekuma/lambda-layers-for-python-runtime.git 
cd lambda-layers-for-python-runtime 
mkdir dist 
docker-compose up --build

2. Based on this guidance: https://www.splunk.com/en_us/blog/cloud/sharing-code-dependencies-with-aws-lambda-layers.html

aws lambda publish-layer-version --layer-name ImageStorageDependencies
    --description "A Python 3.8 runtime with PIL and boto3 installed." --license-info "MIT" --zip-file fileb://output.zip --compatible-runtimes python3.7 python3.8 --region us-east-2

I then choose my layer in the Lamda configuration, but when I run this code:

import json
import boto3
import io
from PIL import Image


def lambda_handler(event, context): 
    #etc

...I get the error:

[ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_function': cannot import name '_imaging' from 'PIL' 

Where exactly am I going wrong?!?
