blank page after SAML user login

[andrea-janna]

problem

After upgrading from version 4.22.0.1 to version 4.22.1.0 when a user authenticates via single sign-on the browser screen stays white but a blue progress bar at the top.
Users that don't have SSO enabled can login normally.
I tested both Chrome and Firefox on Windows.

The Chrome console reports the following 2 errors:

user.js:458 SyntaxError: "undefined" is not valid JSON

versions

Cloudstack 4.22.1.0 on Rocky Linux 10.

The steps to reproduce the bug

1. select "single sign-on" in the login page and press the login button

What to do about it?

@andrea-janna is the API still usable for the SSO user?

@DaanHoogland
I'm not sure if I understood you question but I think the answer is yes, the API is usable.
For instance I can use CloudMonkey authenticating with the apikey and secretkey of the SSO user and successfully execute commands like "list zones" or "list accounts".

@DaanHoogland
In the browser DevTools I can see that after the SSO login the following api functions are called:

• listUsers
• listGuiThemes

The HTTP status code is 200 and I can see the json payload in the responses.

@andrea-janna just to confirm, you're seeing this issue with all SAML users and not just with a particular user?

@shwstppr
Yes I have this issue for the SAML users that existed before upgrading CloudStack and also for SAML users created after the upgrade.
