It looks like the error comes from superset, but it as been installed today and only has default config (one admin user and default roles)

fetchCsrfToken and fetchGuestToken runs without error

thanks

Hello!

Could you clarify which version of Superset you are using? From the Superset stack trace, it seems unable to retrieve user role permissions. Have you configured the guest role in the Superset configuration?

You can find minimal Superset configuration here: Configuration :: Jmix Documentation.

Thanks, I found the issue. I set GUEST_ROLE_NAME = "foo Gamma" and the role didn’t exists in superset because the default name is Gamma.
