Unable to create new illustration, command cancelled

🤣🤣🤣

This is my code:

ActiveXComponent  app = new ActiveXComponent("Illustrator.Application");
Dispatch docs = Dispatch.get(app, "Documents").toDispatch();
Dispatch doc = Dispatch.call(docs, "Add").toDispatch();

 And this is error info:

com.jacob.com.ComFailException: Invoke of: Add
Source: Adobe Illustrator
Description: an Illustrator error occurred: 129 ('')

It happens on this line of code:

Dispatch doc = Dispatch.call(docs, "Add").toDispatch();

And it happens occasionally.
