Admin 5.7.1 Error in Net Core

Hello, it is the first time I am trying to use Admin plugin. (Version 5.7.1)
But I am getting following error when I click one of my services:

AutoQuery.tsx:68 Uncaught (in promise) TypeError: Cannot read property ‘properties’ of undefined
at t.resolveProperties (AutoQuery.tsx:68)
at t.getSelected (AutoQuery.tsx:127)
at t.render (AutoQuery.tsx:220)
at p._renderValidatedComponentWithoutOwnerOrContext (ReactCompositeComponent.js:798)
at p._renderValidatedComponent (ReactCompositeComponent.js:821)

at Object.mountComponent (ReactReconciler.js:45)
at p._updateRenderedComponent (ReactCompositeComponent.js:764)
at p._performComponentUpdate (ReactCompositeComponent.js:723)

My DTO looks like this:

[Route("/Activity/GetPaged/{Limit}/{Page}", "GET")]
public class GetPagedActivitys : QueryDb<Activity>
public string FilterGeneral { get; set; }
public bool RequiresKeysInJsons { get; set; }

And my service like this:
public object Get(GetPagedActivitys request)
var query = AutoQuery.CreateQuery(request, Request);
return WithDb(db => Logic.GetPaged(
requiresKeysInJsons: request.RequiresKeysInJsons

Thank you,

I can’t repro your implementation with what’s provided but this commit should resolve the NRE issue shown in your StackTrace.

Since you already have v5.7.1 you will need to clear your NuGet packages cache to download the latest v5.7.1 that’s now available on MyGet.

Thank you for your quick support.

Error is not thrown anymore, however, I am just getting a blank page.

It is likely I did something wrong with my setup. I will start over in a fresh project and let you know what happens.
