title: The given key was not present in the dictionary - Visual studio SSDT Deploy
body: <p>I have a SSDT project in Visual Studio 2017 and multiple reports working off a shared data source. I can build all the reports and also preview them with the ability to refresh the data. However when I click deploy I receive the error message </p>
  
  <p>Error  : The given key was not present in the dictionary.</p>
  
  <p>I have checked the project deployment details e.g (target sever details, Target Report Folder etc.) and they are all correct. Could anyone advise the best way to debug this error?
