Expected Behaviour
I am having problems with my PHP for the Oauth2 authentication (Access token fetch)
Current Behaviour
I can get the “code” + “state” in my PHP script – but when I try to fetch the access token from “https://oauth.izettle.com/token” I am getting an error message :
_“json={"error":"invalid_request","error_description":"codeverifier cannot be empty"}”
Steps to Reproduce
I have all the code compiling and building in android studio – that is all good - no modifications to the main code - values are setup in iZettleSDK.gradle (githubAccessToken/clientId/redirectUrlScheme/redirectUrlHost)
Context
Failure Logs
_“json={"error":"invalid_request","error_description":"codeverifier cannot be empty"}”
