Auth0.js login and signup validation documentation

Hi, I am trying to localize my validation errors during auth0 login and signup. I use the classic universal login feature for users to authenticate.

  • Which SDK this is regarding: auth0-js
  • SDK Version: ^9.19.0

I haven’t found the correct documentation that would lead to an exhaustive list of all the possible validation errors I would encounter, or for a way to switch up locale automatically.

I had hoped this link would help with this matter, but the errors do not correspond to the output from what has been listed.

Here is a sample output in the console.

// empty input fields (endpoint is https://*endpointID* 
status: 400
message: "invalid username"
