If you are not using credentials this error appears when you are trying to set the request validator in put and post method, to validate parameters, headers and body. In this case if I’m not wrong it will look for credentials on the header to refuse the request. To summarize, if you are not ready to provide credentials and want to keep them open, don’t enable that option in the request validator. I read on a reddit thread, that this method worked for someone. Unfortunately it was like 2 years ago, so now It is possible to not work. If you are a beginner in IT and want to create website you can use api scrapping with instant setup, to get very vast a part of code you need.
