Attempting to PUT Object, but get error SignatureDoesNotMatch

I am trying to upload to a space with LUA from scratch. I have spent many hours trying to solve this problem, looking over DigitalOcean API docs and Amazon S3 documentation, along with many other resources. Help would be greatly appreciated.

Here’s the code I’m using:

The error here doesn’t immediately stand out, but I’d like to point out there is a test suite for AWS V4 signatures:
https://docs.aws.amazon.com/general/latest/gr/signature-v4-test-suite.html

Write a testcase runner for your Lua code to use those tests, and you’ll probably trace down the error in no time!
