Trying to make a javascript script to sign automatically a pdf file

[CaraxIT]

I tried to make a script to automatically sign a pdf file on Adobe Acrobat DC when called using a folder level script but the only results i've got is this 

sign(this)
GeneralError: Operation failed.
Field.signatureSign:30:Console undefined:Exec
The document could not be signed.

There was an error when attempting to commit this signature. The document was not saved.

The file may be read-only, or another user may have it open. Please save the document with a different name or in a different folder.

undefined

Here is my code if you see any flaw

var sign = app.trustedFunction(
	function(doc){
		app.beginPriv();

		var ppklite = security.getHandler("Adobe.PPKLite");

		ppklite.login("password", "/I/Certificates/test.pfx");
		doc.addField("Text1", "signature", 0, [0,100,100,0]);
		var f = doc.getField("Text1");

		var myInfo = {
			password: "password",
			location: "Country, IN",
			reason: "I am approving doc document",
			contactInfo: "mail@gmail.com",
			appearance: "basic",
			mdp: "allowNone" 
		};
		console.println(f.signatureSign({oSig: ppklite, oInfo: myInfo,cDIPath: "I/gg.pdf", bUI: false }));
		ppklite.logout();
		app.endPriv();}
	);

It doesn't work on new or on file pdfs. I am a complete debutant in adobe JS and I tried using the documentation but I don't understand why it doesn't achieve anything.

Are you able to do it manually?

Yes, I have no problem to do so but I need it automated

I don't know what the diPath parameter means here but this is certainly wrong as all DIPaths start /

Also, I would not try to work in root directories, Acrobat may reject them.

cDIPath: "I/gg.pdf"

Thank you ! That was it

Hi all,

does anyone know if i can do the same with a certificate which is stored in the windows certifcate store?

I know the path, but the file is a cryptical *.sys file, and a password was not requested when setting up the certificate.

Sorry the screenshots are german. Hopefully everyone can understand.

Thx for any help.

Cheers

Michael
