Batch image trace in Illustrator

Is there any way to batch trace images located in a directory with High fidelity option?

I created an action including open an image, image trace it with high fidelity option, save it as PDF and close. However, when I batch do the tracing for images in a folder, the output is only black and white ones. I reckon the option setting action isn't captured when I create the action. So how to solve it?
