ADS1115 analog gain signal module - how to run it with espruino?

hi, wanted to use this module again,
used this code on the green Espruino

    I2C1.setup({ scl : B6, sda: B7} );
    var ads = require("ADS1X15").connect(I2C1); // <--- this now pulls everything from the internet
    ads.setGain(4096); // +/- 0.256mV
    ads.getADC(0, function(val) {
      console.log("Reading: "+val);
    });

    function everySecond() {
     ads.getADC(0, function(val0) {
      ads.getADC(1, function(val1) {
       ads.getADC(2, function(val2) {
        ads.getADC(3, function(val3) {
         console.log(val0,val1,val2,val3);
        });
       });
      });
     });
    }
    setInterval(everySecond, 1000);

and got this error

in function called from system
Uncaught Error: Invalid differential channelSpec 0
 at line 1 col 157
...ifferential channelSpec "+a);c|=e}c|=d[this.gain];this.write...
                              ^
in function "getADC" called from line 10 col 7
     });
      ^

before it was working well
is something wrong with the code? or module from "require function"?
