My main complaint with that roadmap is that it changes often. Your data today may not be accurate in a couple of weeks
oh nevermind, I misunderstood your question
You could check the composer.json file of each tagged release?
If you inspect the code on the frontend so you can see the actual HTML. What does the "name" attribute say?
If you're using Member Profiles, make sure the Email address field is present on the form
Your error is caused on Line 80 in MemberProfileValidator. To troubleshoot the issue, you're dumping out the $data array to see the field names that are available
- $other = ....
What happens if you put a
var_dump($data);die; right before that line?
It's basically complaining that $data['Email'] doesn't exist
