Though I don’t know the full details of your setup, I can take a stab at what advice to give…
If you’re wanting a customised lock.js login experience, it’s often simpler to add your configuration to the login page customisation page on Auth0 as opposed to including lock.js as part of the front end (these variables won’t do any good passed in the Auth0Client).
Try this guide to customising lock using these options.
This could be a good first step?
