Hi!
We are trying out Service API on our Epi Commerce version 12.12. We follow the guide here: https://world.episerver.com/documentation/developer-guides/Episerver-Service-API/installation-and-configuration/. When browsing the site we get the following un-explanatory error:
2021-03-05 14:32:44.445 [(null)] [1] ERROR EPiServer.Framework.Initialization.InitializationEngine.InitializeModules(:0): Initialize action failed for 'Initialize on class EPiServer.ServiceApi.IntegrationInitialization, EPiServer.ServiceApi, Version=5.3.1.0, Culture=neutral, PublicKeyToken=8fe83dea738b45b7'

Thankful for any help.
