Failure TypeError: Cannot read properties of undefined (reading 'toString')

I got error like in title.

I am simple using it like this:

reader
      .read(4, 16, 16)
      .then((cardHeader) => {
        return nfcCard.parseInfo(cardHeader);
      })

    at nfcCardTool.getHeaderRawValues (C:\Users\Radoslaw\Desktop\nfc-pcsc-master\nfc-pcsc-master\node_modules\nfccard-tool\lib\nfccard-tool.js:57:25)
    at nfcCardTool.parseInfo (C:\Users\Radoslaw\Desktop\nfc-pcsc-master\nfc-pcsc-master\node_modules\nfccard-tool\lib\nfccard-tool.js:274:32)

Card is Mifare classic.
