Hey @SethPyle376 👋 Thanks for the PR! It looks like the snapshots didn't include corresponding AWS validations. Did you manually edit these or run and record your test output against AWS? You can see some guides on how we write tests for our local emulator and maintain parity with AWS in the testing docs. In particular, I'd look at the parity testing docs. Since this PR will definitely require re-recording AWS behaviour, I'll just run the necessary snapshot tests against AWS and update your feature branch with the corrected files. You'll retain full authorship of the PR since we squash commits anyway. Does that work for you? 🙂 cc @baermat |

FYI i added the webserver configuration needed to make this change work. specifically we needed to increase the default limit for form-encoded requests. relevant code in werkzeug that lead to errors: |

Thanks for the contribution @SethPyle376, and thanks for running the tests @gregfurman! The change turned out a little trickier than it seemed on the surface, but with the additional update of the form parser memory limit we should be good to go!
