Ok Thanks for the quick responses!
So that worked, though I had to write
password = jarray.array(, Integer)
as
password = jarray.array(, 'i') to pass the java type.
Now, to extract the results. I see the values I want in the "Raw Outputs" of the log
But in my scripting I am getting the coerced outputs as results[2] from callMethod. Is there a way to pull the raw outputs into an array?

No, the raw outputs are often types from the OPC UA library and need to be converted into types that can be used from Ignition / scripting. They're only printed there for debugging purposes.
The corresponding representation of an OPC UA ByteString in Ignition is a Short Array (java.lang.Short[]).
Excellent
I was able to get the array back!
resultArray = system.opcua.callMethod(connectionName, objectID, methodID, inputs)[2][0]
I know [2] here is the list of output values from the callMethod Function.
If I didn't then take [0] from that my result was returning as the whole Object with the value [[Ljava.lang.Short;@xxxxxxxx, 0].
Then I converted this data to a string with:
resultString = ''.join(chr(character) for character in resultArray) since my RFID data is ascii bytes.
In case someone else in the future needs that.
