Hi all I have been using the sample project that is available to download after creating Single Page App at developer.okta.com it’s in the general tab of such project:
What error are you seeing ? Any clues from console (dev tools) or from the failing request in the network tab ? You could also check for failing events in Okta System Log.
Also, make sure the type of client created in okta for example.okta.com is similar to the example app.
