saml/sso fail

I need some help on this. I have implemented everything as per the 2 projects

However when I load the UI screen it redirects to ssocircle.  I login and it redirects back to /saml/sso url on the springboot app.

But I just get an error

The request was rejected because the URL was not normalized.

What should I see after successful login?

Can you please assist asap?
