When using tools like Auth0 or other services using external cookies, make sure to have “Block third-party cookies” setting disabled in your browser.
Here’s how to do it in chrome:
- Search for “Cookies”
- In my case it was located in Site settings > Cookies and site data > Block third-party cookies
The reason I post it on TIL is that there were no issues apparently, the error appeared in URL and it was pretty hard to debug it. Just a heads up for you to check it whenever you are dealing with third-party services.
