AS3 - StageWebView - Error #2044: Unhandled error:. text=PDFError

[Isabelle LOYER]

Hello,
I try to display a pdf with a StageWebView component :

var SWV:StageWebView = new StageWebView();
		var swvHeight:Number = container.height-75
		var swvWidth:Number = container.width;
		var swvYCoord:Number = 75;
		SWV.stage = container.stage;
		SWV.viewPort = new Rectangle(0, swvYCoord, swvWidth, swvHeight);
		var urlToLoad:String = urlCourTXTServ;
		SWV.loadURL(urlToLoad);

For sample, urlToLoad is like that : 'http://127.0.0.1:10088/MyApp/Data/Customer/File/Demo/w4.pdf'

The path is good, the pdf file exist and I can load it with navigateTourl.

But when I execute the code, this error appear Error #2044: Unhandled error:. text=PDFError

Where I'm doing wrong?

Thanks for helping.
