NFC module (PN532) not working

Hello guys
I've set my module to use I2C and using following example:

I2C1.setup({scl:22, sda:21,});
var nfc = require("PN532").connect(I2C1);
print(nfc.getVersion());
nfc.SAMConfig(); // start listening
setInterval(function() {
 nfc.findCards(function(card) {
  print("Found card "+card);
  card = JSON.stringify(card);
  var leds = [LED1,LED2,LED3];
  if (card=="[147,239,211,128]") digitalWrite(leds,1);
  if (card=="[249,192,235,164]") digitalWrite(leds,2);
  if (card=="[4,99,129,114,72,52,128]") digitalWrite(leds,4);
 });
}, 1000);

And I got I2C errors:

Any ideas why basic example does not work? Using ESP32 module.

Seems like v197 will work with PN532. But not in v198. Only change what I found is here:

@Gordon can you figure out why PN532 does not work in newer versions?

Can you try : I2C1.setup({scl:22, sda:21, bitrate:50000});?

And which board is this on? It looks suspiciously like an ESP8266/32?
