<p class="MsoNormal"><span lang="DE-AT"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Setup: IDP v4.3.1 configured as SAML Proxy with Discovery Service activated.

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">On trying HelloWorld Plugin, it produces an uncaught Exception. Probably because Upstream Relying Party is unknown prior to discovery, but somehow already expected, or discovery is skipped.

<p class="MsoNormal"><span lang="EN-US">Regular authentication works fine, it is just an issue with the HelloWorld Plugin.

<p class="MsoNormal"><span lang="EN-US">If I disable discovery and pass a single Entity ID for the SAML Flow, the plugin works again.
