CreateShape with type "line" causes expected error when building

[prudentcircle]

Describe your problem:

Api.CreateShape with "line" as a parameter causes errors when buliding a PPTX document.

Be clear in your description of the problem.
Open an issue with a descriptive title and a summary in complete sentences.

I used below Docubuilder code to try to generate a PPTX document.

var oFill = Api.CreateNoFill();
var oRGBColor = Api.CreateSolidFill(Api.CreateRGBColor(255, 111, 61));
var oStroke = Api.CreateStroke(0, oFill);
var oShapeLine = Api.CreateShape("line", 25.4*36000, 1*36000, oRGBColor, oStroke);
oShapeLine.SetPosition(0, 748800);
oSlide.AddObject(oShapeLine);

The process errors out when executing the following step

oSlide.AddObject(oShapeLine);

However, the error goes away when I try to create Shape of "rect".
In the API documentation, there is difference between "Line" and "Rect" in terms of what argument you have to use.
However, in real life, using "line" errors out with the same arguments.

Steps to reproduce the problem:

Create a docubuilder file with the following content

builder.CreateFile("pptx");
var oPresentation = Api.GetPresentation();
var oSlide = oPresentation.GetSlideByIndex(0);
oSlide.RemoveAllObjects();
var oFill = Api.CreateNoFill();
var oStroke = Api.CreateStroke(0, oFill);
var oShapeTitle = Api.CreateShape("rect", 127.1* 36000, 9.4* 36000, oFill, oStroke );
oShapeTitle.SetPosition(266400, 266800);
var oDocContent = oShapeTitle.GetDocContent();
var oParagraph = oDocContent.GetElement(0);
oParagraph.RemoveAllElements();
var oRun = Api.CreateRun();
var oTextPr = oRun.GetTextPr();
oRun.AddText("test-title");
oTextPr.SetFontSize(32);
oFill = Api.CreateSolidFill(Api.CreateRGBColor(51, 51, 51));
oTextPr.SetFill(oFill);
oTextPr.SetFontFamily("Malgun Gothic");
oParagraph.AddElement(oRun);
oParagraph.SetBold(true);
oParagraph.SetJc("center");
oSlide.AddObject(oShapeTitle);

var oFill = Api.CreateNoFill();
var oRGBColor = Api.CreateSolidFill(Api.CreateRGBColor(255, 111, 61));
var oStroke = Api.CreateStroke(0, oFill);
var oShapeLine = Api.CreateShape("line", 25.4*36000, 1*36000, oRGBColor, oStroke);
oShapeLine.SetPosition(0, 748800);
oSlide.AddObject(oShapeLine);

Api.Save();
builder.SaveFile("pptx", "test_file.pptx");
builder.CloseFile();
