I think the Error is from here:
All preflight request to SHibboleth IdP is from this origin:
‘https://s.org/jupyterhub/user/yuqiang/api/kernels?1711651794595’
This Error only occurs in my windows browser. There is no problem with my Iphone Browser (Chrome and Safari)
Why should this URL send this request? Is it trying to check the identity again?
Causes which are excluded:
Authenticator: I just used Dummy authenticator, this CORS error keeps occuring. So I think this has nothing to do with Authenticator.
