register page throwing error on ‘errors’

I have created a custom php file for new user registration fields, validation and post values to database. It is in /plugins/theme-my-login-custom.php

But validation is not working properly.

On our dev instance, there is a JS error on ‘errors’. It shows the error messages for missing values, but it adds them to the database anyway. I’ve tried various stuff – disabling plugins / updating / looking for conflicts / disable Ajax in TML (that was the one recommendation I found when Googling this error) but these did not fix it.

To recreate, https://demo2.visitaccess.com/safsf/register/ and only put values in for username and email, then submit. When the errors are shown, the values should not post to the database, but they are posting. Oddly the code I have works perfectly fine on my local instance, and no values are entered in database if error messages show.

If you can offer any insight, I would appreciate it.
