How can I connect Puck2.js to PN532 NFC/RFID ?

Hi,
I have a PuckJS 2 with 2v06 and a PN532 NFC v3 module from Elechouse, connected as follows:

Puck.js_D28 to PN532_SCL,
Puck.js_D29 to PN532_SDA,
Puck.js_3V to PN532_VCC,
Puck.js_GND to PN532_GND,

Puck.js works fine and the red LED on the PN532 is also active.
Actually I use the Espruino Web Ide Tool, so:
1) I wrote the require("PN532"); on the right side;
2) sent with "Send to Espruino button" - the loading was OK (screen refreshed);
3) I tried to run it as described in the example for PN532 ( scl:B6 and sda:B6 changed to D28 and D29 );

I see now the following on the web console:

I2C1.setup({scl:28, sda:29});
=undefined
var nfc = require("PN532").connect(I2C1);
={
i2c: I2C1
}
print(nfc.getVersion());

Can somebody help me, what could be the problem?
Thank you!
