Could not load type 'ADSK.AIT.Common.API.Services.IRevitIniService'

When running the model checker module in Clarity I receive the following error.
Could not load type 'ADSK.AIT.Common.API.Services.IRevitIniService' from assembly 'AIT.Common.API, Version=9.1.8503.0, Culture=neutral, PublicKeyToken=null'. Developer Info: at Cohort.RevitTaskPlugins.ModelChecker.Execute(Task t) at CohortRevitTaskServer.Controller.runOneTask(String artifactPath, String projectArtifactPath, Document& doc, OpenModelOption openModelOptions, String loadErrors, KeyValuePair`2 oneTaskToProcessor, TaskWrapper parentTask, SecurityManifest security)

What could be causing this?

We are running 9.1 unfortunately. I'll try to get my IT team to upgrade us to 9.2

David,

Do you know what version of Interoperability Tools you have installed?  We only support 9.2.2 now (because Autodesk puts breaking changes in with every update).

We should have a nicer message than that - we'll look into that. But I suspect on that task server you only have 9.1 of AIT installed.

Best Regards,

Matt

Which version of Clarity and which version of Revit was running?

We recently discovered we had a mismatch on - I forget... Revit 2020? 2021?

That is being worked on for a near-term update.
