From a user’s point of view: I really like the Visio Services in SharePoint 2016
From an administrator’s view: finding the source of an error in Visio Services can be a real pain!
Failed to get raster diagram for Visio file: Default Page ID Exception
The error for the user is not very helpful:
Visio Services was unable to display the requested page because it does not exist within this Web Drawing. To resolve this issue, make sure to request a page that exists within this Web Drawing.
The error message in the ULS log – nah:
Failed to get raster diagram for visio file https:///.vsdx page default page ID Exception : System.ServiceModel.FaultException`1[Microsoft.Office.Visio.Server.GraphicsServer.VisioGraphicsServiceFault]: The creator of this fault did not specify a Reason. (Fault Detail is equal to Microsoft.Office.Visio.Server.GraphicsServer.VisioGraphicsServiceFault).
I was able to open the document in Visio 2016 and everything looked fine. I compared this file to another, which rendered fine. The difference was very hard to spot: The heading of the tab displayed was italic and not regular as in the good file.
An italic tab name indicates, that this is a background page and not a regular page. After changing the page type, everything worked as expected.
