Tutor installed propertly, but I can´t log in

Hello, I just installed Tutor with Olive, and both lms and cms urls work just fine, I can navigate to both.
I created a superuser to login, but as soon as I try to Login in Studio, or in the lms site, I get the errors:
bug/1173575, non-JS module files deprecated.

anyone can help please?
Thank you very much in advance!
