State error with auth0-js and iframe implementation

Help
1

Hi There,

I have some difficulty to found an alternative or solution
I use "auth0-js": "9.15.0".

My case:

I use auth0 on my application for authentication with new Auth0 Universal Login and it works.
The problème is that some customers use iframe in her owns application to use my application.

With new Auth0 Universal Login we can’t use Disable clickjacking protection for Classic Universal Login for iframe usecase, so we can’t log with iframe.

For get around the problem i use popup from auth0-js to log user outside the iframe.

My implementation:

WebAuth

      const client = new auth0.WebAuth({
        domain: '[domain]',
        clientID: '[clientID]',
        redirectUri: '[redirectUri]',
        responseType: 'token id_token',
        scope: 'openid profile email',
      }),

popup

client.popup.authorize(
        {
          redirectUri: auth0Store.redirect_base_url + '/auth0?iframe=true',
        },
        function (err, authResult) {
          if (null !== err) {
            //logout
          }
          
          //use authResult.accessToken
        }
);

popup close

client.popup.callback();

With iframe and chrome browser my authResult is undefined.
When i try to replace client.popup.callback() by client.parseHash i have an error

{
error: invalid_token, 
errorDescription: `state` does not match., 
message: `state` does not match.
}

This work with cross domain and Firfox, but doesn’t with Google chrome.
I think this come from cookie management but i don’t know how to resolve this problem

Thank you in advance for your answer =)

I had the same error, and after some research, I found a closed issue on GitHub:

Issue #1077

And after adding the following to the WebAuth initialization object everything worked fine:

const client = new auth0.WebAuth({
domain: ‘[domain]’,
clientID: ‘[clientID]’,
redirectUri: ‘[redirectUri]’,
responseType: ‘token id_token’,
scope: ‘openid profile email’,
__tryLocalStorageFirst: true
}),
