    Models Builder, 401 error when running custom tool in Visual Studio

    Hi guys,

    Thought I'd share this in case anyone else comes across it.

    We've been using the Models Builder tool in Visual Studio for a while with no issues.

    Friday, I setup my project on a new machine, and couldn't get Models Builder to work. On running Fiddler, I found that the initial call it makes to the back office was returning a 401 "Unauthorised" error (to /Umbraco/BackOffice/ModelsBuilder/ModelsBuilderApi/ValidateClientVersion).

    Cut a long story short - if the credentials you provide to Models Builder have certain characters in the password, Models Builder fails to authenticate with the back office (presumably some missing encoding?).

    Just posting this in case someone like me tries to find the answer using Google 😊
