Format of font "Courier" is not supported for new composite fonts

I am attempting to create a pdf document which uses the standard “Type 1” fonts. When I try to add a Type 1 font to my page resources (“Courier” for example) I receive an exception stating that:

Format of font “Courier” is not supported for new composite fonts

I am using Aspose.PDF version 23.8.0. Here is the code that I am using to create the document:

private void CreatePDF_Low()
{
    Document doc = new();

    Aspose.Pdf.Page page = doc.Pages.Add();

    Aspose.Pdf.Text.Font font = FontRepository.FindFont("Courier"); 

    page.Resources.GetFonts(true).Add(font, out string fontResName);

    page.Contents.Add(new GSave());
    page.Contents.Add(new BT());
    page.Contents.Add(new SelectFont(fontResName, 16));
    page.Contents.Add(new MoveTextPosition(0, 720));
    page.Contents.Add(new ShowText("the quick brown fox jumps over the lazy dog", font));
    page.Contents.Add(new ET());
    page.Contents.Add(new GRestore());

    doc.Save(@"your_favorite_filepath");
}

I have found that using the higher-level TextFragment object allows me to successfully use Type 1 fonts. For instance:

private void CreatePDF_High()
{
    Document doc = new Document();
    // Add page to pages collection of Document object
    Aspose.Pdf.Page page = doc.Pages.Add();
    TextBuilder builder = new TextBuilder(page);
    // Create text paragraph
    TextParagraph paragraph = new TextParagraph();
    // Set subsequent lines indent
    paragraph.SubsequentLinesIndent = 20;
    // Specify the location to add TextParagraph
    paragraph.Rectangle = new Aspose.Pdf.Rectangle(100, 300, 200, 700);
    // Specify word wraping mode
    paragraph.FormattingOptions.WrapMode = TextFormattingOptions.WordWrapMode.ByWords;
    // Create text fragment
    TextFragment fragment = new TextFragment("the quick brown fox jumps over the lazy dog");
    fragment.TextState.Font = FontRepository.FindFont("Courier");
    fragment.TextState.FontSize = 12;
    // Add fragment to paragraph
    paragraph.AppendLine(fragment);
    // Add paragraph
    builder.AppendParagraph(paragraph);

    doc.Save(@"your_favorite_filepath");
}

works just fine.

I am not sure what I am doing wrong that causes the exception to be thrown in the first example. Any help would be very much appreciated.
