"Uncaught TypeError" on the "Universal Login" page

Hi,
after some changes, we started to get “Uncaught TypeError: Cannot read properties of null (reading ‘value’)” on the “Universal Login” page.

login-console-error

And it doesn’t block the UI.

The link in the error leads to the block of code:

login-console-error-in-code

I found an additional block of code that leads to the error compared to one of our other tenants that has no this error on the login page:

login-console-error-in-code-compared

Does anyone have similar behavior?
Maybe our tenant config is wrong on some points?

we are facing same issue

Same issue here.
Happens also with the latest version 2.1.0

4

We are facing the same issue as well!

5

Ugh, we started running into this issue as well and it’s making our cypress E2E tests fail… Please fix this!

6

We are also facing this issue with our cypress tests :frowning:

7

We are having the same error on our Cypress tests

It’s a hack, but if you need cypress to pass while dealing with this, catch and muffle the error within your cypress login action (if that is your approach):

    cy.origin('https://auth.your-auth0-domain.com', () => {
      cy.on('uncaught:exception', (e) => {
        if (
          e.message.includes("Cannot read properties of null (reading 'value')")
        ) {
          // we expected this error, so let's ignore it and let the test continue
          return false;
        }
      });
    });

We have tried this already. Doesn’t seem to work when running in CI

Having the same issue.

Hey there everyone!

Thanks for reporting that! I just reached out to one of our engineering team to troubleshoot that. As soon as I have the answers I’ll make sure to relay them here. Thank you!

13

Can you confirm what SDK are you using?

14

Cypress version 12.9.0

16

Okay the team is aware of the problem and they are already working on a fix. Will let you know once I have updates to share!

17

In our case it is @auth0/auth0-spa-js: 1.22.6

18

The error also appears for the last version 2.0.6 of SDK @auth0/auth0-spa-js.

19

It’s still not resolved but one of our engineering teams is working on that. Thank you for your patience!

Hey there everyone!

A fix has been merged and should be deployed soon. This seems to only affect automated tests and doesn’t affect authentication itself.

21

@konrad.sopala Should we do something in our side to get rid of this error (e.g. maybe upgrading the auth0 package to a specific version? if that’s the case please let us know what version)?

22

Sure! For now no actions needed.
