[Unity-idm-discuss] NullPointerException on OAuth Auth endpoint

[Sander A. <sa....@fz...>]

Hi Krzysztof,
hi Roman,

we got a report where an user got a NullPointerException on the auth
endpoint, using the OIDC-agent:

HTTP ERROR 500 java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because "scheme" is null
URI:    /oauth2-as/oauth2-authz
STATUS:    500
MESSAGE:    java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because "scheme" is null
SERVLET:    pl.edu.icm.unity.oauth.as.webauthz.OAuthParseServlet-12f306f7
CAUSED BY:    java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because "scheme" is null
Caused by:

    at pl.edu.icm.unity.oauth.as.webauthz.OAuthParseServlet.doGet(OAuthParseServlet.java:112)

The user used this return URL: edu.kit.data.oidc-agent:/

I have two questions about this. First of all is such an URL supported
by unity? The second question would be if it would make sense to catch
this Exception and show a proper error message instead?

Best regards,
Sander
