Good morning everybody,

I'm updating an internal application code to support Trados 2022SR1. This application that creates projects on demand based on an xml file, 

I have an error at the AddFolderWithFiles stage. I suspect this could have something to do with the recent changes on languages retrieval.

To create the project i build and populate a ProjectInfo object, which contains the correct languages codes as it seems.

Languages are retrieved through the new LanguageRegistryApi.Instance.GetLanguage(lang) method.

on calling AddFolderWithFiles(folder_path,true) i get 

System.ArgumentNullException:Value can't be null'

Parameter name: path2"

This is the project creation code part:

This is the value of "myParams.SourceFilesFolder:

The is the error with the stack trace:

I really hope someone can kindly point me to the right direction in fixing this issue. I still have the suspect the issue has something to do with the languages during project creation.

I've read documentation at https://developers.rws.com/studio-api-docs/apiconcepts/releasenotes/tradosstudio2022sr1.html?_gl=1*1n36q6l*_gcl_au*Mzk0ODg5ODE2LjE2ODQ0MDM0MDY.*_ga*MzczODM5NDk4LjE2MTgyMzk5NjY.*_ga_J0Z9C6G83T*MTY4OTU4NTYwNy42My4xLjE2ODk1ODYyODQuMC4wLjA.

but it's not clear if there should be any change during project creation.

Thank you in advance for reading.
