UPDATE Problem has been resolved
What I Wanted to Do
I wanted to active 2FA over this link. After seeing the “What should we protect” window and pushing the “submit” button, I thought I could insert a code into my Authenticator app.
What Happened Instead
Instead, I saw an error message:
child “mode” fails because [“mode” is required], child “step” fails because [“step” must be one of ]
I tried it on several days, every time with the same result.
- Go to the 2FA page
- Press submit
- See the error
