RFID module RC522 interfaced to Pico results in various Uncaught Error MFRC522 Request Errors

Thank you Gordon, that answered my first two questions.

Anybody see anything glaringly obvious as to why this doesn't return the expected result?

Using the existing module 'read' function and adding a function to the instance object, while maintaining the same existing coding format.

mfrc522Instance.getver = function() {
  var ver = this.r(R.VERSION);
  console.log("[766] version: " + ver); 
};

Using the spec p.37

37h VersionReg shows the software version

and p.66

9.3.4.8 VersionReg register Shows the MFRC522 software version
