Hi Community,   For a project we want to implement offline PWA. For this we have rewritten our online application to offline modus. We have done this by using NFs and rewrite domain models where needed. We do not have any mendix errors present, so we should think we could run the application. Unfortunately, we cannot run the application due to an error. We have raised a support ticket and escalated it to R&D department, but with no success yet.  We have tried to following potential solutions change security to Prototype delete or change database port delete PWA navigation profile rewrite all currentUser tokens include excluded pages Has anyone seen this error before? Does anyone know what causes it?   System.AggregateException: One or more errors occurred. (Value cannot be null. (Parameter 'key')) (Value cannot be null. (Parameter 'key')) (Value cannot be null.
