I am having a problem in the sample code for the OneDriveCustomizer app.
The following line (in the CreateSharePointContext method doesn't get the spAppWebUrlString.
string spAppWebUrlString = TokenHelper.EnsureTrailingSlash(httpRequest.QueryString[SharePointContext.SPAppWebUrlKey]);
If I debug the code and manually set it then the rest of the code runs through as expected and changes the theme to orange.
Has anyone else come across this issue or know how to fix it?
