System.NullReferenceException

[s1jtaylor]

I'm getting the following error when opening up a pbt and changing the connection to a new server. Any ideas?

PowerBINonFatalError:
{"AppName":"PBIDesktop","AppVersion":"2.81.5831.1181","ModuleName":"","Component":"Microsoft.Mashup.Evaluator.ChannelMessenger","Error":"Microsoft.Mashup.Host.Document.SerializedException - System.NullReferenceException","MethodDef":"CreateChannel","ErrorOffset":""}

I cannot reproduce the issue. You may try the latest version of Power BI Desktop and create a support ticket for assistance.
