TypeError: can assign only bytes, buffers, or iterables of ints in range(0, 256) when processing request.json using werkzeug 2.2.3 and higher #20
Description
When calling request.json in DELETE or POST calls I receive the following stack trace error:
Traceback (most recent call last):

As title suggests I am using main branch of flask-lambda, flask 2.3.2 and werkzeug 2.3.6.
When app is run locally as a regular Flask app the request.json call does not result in TypeError.
