Passwordless login: "We're Sorry, Something Went Wrong"

Hi there,

I enabled passwordless login. However, when entering an email adress, the form just sais “We’re Sorry, Something Went Wrong”.

I’m getting this error in the developer console:

Also, is the new universal login page able to handle passwordless login?

Thank you very much in advance.

(Adding it to the “Allowed Web Origins” list does not fix it)
