Hyperlink to file throws exception

[nicolajteknikteamet]

When setting a hyperlink to filename an exception is thrown "Hyperlink is invalid.".
Powerpoint should be able to link to other presentations.

Code below throws the exception.

using var sourcePresentation = SCPresentation.Open("SourceTemplate.pptx");
if (File.Exists("NewPresentation.pptx"))
{
File.Delete("NewPresentation.pptx");
}

sourcePresentation.SaveAs("NewPresentation.pptx");

//create four shapes with a long text in each
var slide = sourcePresentation.Slides[0];
for (int i = 0; i < 4; i++)
{
var shape = slide.Shapes.AddRectangle(150, 100 + 100 * i, 500, 50);
shape.TextFrame.Text = "This is a long text #" + i;

shape.TextFrame.Paragraphs[0].Portions[0].Hyperlink = "SourceTemplate.pptx";

}

sourcePresentation.Save();
