We are upgrading from Studio/Groupshare 2017 to Studio/Groupshare 2022 and are adding a server based TM to our local project. When setting credentials to the translation memory URI, we get this error (Stacktrace at the end):

String reference not set to an instance of a String.
Parameter name: s

This is the code:

            _tpConfig.Entries.Add(tmprov);

            _tpConfig.OverrideParent = true;

            _tradosProject.UpdateTranslationProviderConfiguration(_tpConfig);

            _tradosProject.Credentials.AddCredential(tmprov.MainTranslationProvider.Uri, false, Account.UserName, Account.Password);

            _tradosProject.UpdateTranslationProviderConfiguration(_tpConfig);

URI is: sdltm.XXXXXX

Same URI (other host) as we have in current GS2017/Trados2017 environment.

Setting this, works without any exceptions, but when pretranslating process has no access to referenced TMs:

_tradosProject.Credentials.AddCredential("http://XXXXXX", false, Account.UserName, Account.Password);

Code is same as described in your documentation Adding the TM to the Project (rws.com)

And as we have used with Trados 2017/GS 2017, where it works without any issues.
