Completed 422 Unprocessable Entity [Rails 5 API only, React with J-Toker]

[nthock]

Sorry that I have to post this issue as I am stuck for a few days. I am using Rails 5 API-only app hosted with Heroku. I try to use React as the front end to do user authentication with J-Toker.

However, I keep getting the error "Completed 422 Unprocessable Entity". I have set the settings using Rack Cors gem to allow origin from any domains. So I really don't know what is wrong. Is there anyone who experience this can share how do you deal with this issue:

Here's my code:

application_controller.rb

class ApplicationController < ActionController::API
  include DeviseTokenAuth::Concerns::SetUserByToken
  respond_to :json

end

In my React:

Registration_form.js

Auth.configure({
  apiUrl: <Heroku URL>
});

handleSubmit = (e) => {
    e.preventDefault();
    this.props.form.validateFieldsAndScroll((err, values) => {
      if (!err) {
        this.setState({ email: values.email });
        this.setState({ password: values.password });
        this.setState({ password_confirmation: values.password_confirmation });

        Auth.emailSignUp({
          email: this.state.email,
          password: this.state.password,
          password_confirmation: this.state.password_confirmation
        });

      }
    });
  }

I do not think the issue lies with J-Toker. Really thank you so much for your help on this.

Was having the same issue myself, but I think I found the problem. In the DeviseTokenAuth Registrations Controller it is expecting a "confirm_success_url" param to be included along with the email, password, and password_confirmation. Try adding that and seeing how it goes.

Workaround posted, so closing this one for now.

In the request response, you can inspect the error message to see why your request got denied. Mine was

"errors":{"password":["is too short (minimum is 8 characters)"],"full_messages":["Password is too short (minimum is 8 characters)"]}
