Error log when I call webgazer.begin()

I am using webgazer to do some eye tracking experiment, and find every time there is an error log in terminal.

@newbeginnerfuqing you can copy over the .map file to resolve this warning. It provides better debugging information, but it's optional.

@jeffhuang Thanks for your reply! But these days another error occur, it report type error : load fail on webgazer.begin(), and I've tried official demo, it have the same problem.
