The 1.4.0 release tightened SAML request validation.

Rather than leverage your reverse proxy to rewrite the path from
"/guacamole" to "/", I would recommend just reploying the webapp at the
desired path to begin with, and reconfiguring your reverse proxy
accordingly. The webapp can be deployed directly at "/" by renaming the
.war file to "ROOT.war".
