NullReferenceException in authenticate

[vimarx]

I have this issue in production in a web app, it is difficult to catch in a debug environment.

Objectspace is not Null , login parameters also aren't null, How can I go deeper?

this issue is not new (a couple of months at least), and it is making me crazy... Thanks.

do u use the MS Office packages?

[vimarx]

not direct, may be some lost reference?

[apobekiaris]

if not then I would try to gather more info by overriding the XafApplication CreateLogonObjectSpace which is the one that returns a null objectspace

        protected virtual IObjectSpace CreateLogonObjectSpace(Type objectType) {
            CheckCompatibility();
            IObjectSpace objectSpace = null;
            IObjectSpaceProvider objectSpaceProvider = GetObjectSpaceProvider(objectType);
            INonsecuredObjectSpaceProvider nonsecuredObjectSpaceProvider = objectSpaceProvider as INonsecuredObjectSpaceProvider;
            if(nonsecuredObjectSpaceProvider != null) {
                objectSpace = nonsecuredObjectSpaceProvider.CreateNonsecuredObjectSpace();
            }
            else {
                objectSpace = objectSpaceProvider?.CreateObjectSpace();
            }
            return objectSpace;
        }

do u use the MS Office packages?

Xpand Office or DX office?

[apobekiaris]

looking again at the GetObjectSpaceProvider method we see that is a Type location failure problem which tell us that something is wrong with our boot so i would verify that by check the type.Assembly,Location and AssemblyQualiedName of the objectType

[apobekiaris]

i meant the Xpand MS packages

[apobekiaris]

so to clear my thoughs overrider the CreateLogonObjectSpace and when objectspace is null return the type.Assembly.Location, type.AssemblyQualiedName etc.

[apobekiaris]

and by return i really mean trace them in the log :)
