How to pass multiple parameters from robot script to python

Question

My requirement is to update a JSON structure and then write it into a file using key value pair. Below is my Python script, based upon the values for TESTVER, TESTLVL and TESTGRP we will receive from Robot script we need to update it:

cmd = 
"""{
        "TESTVER": "v1",
        "TESTLVL": "Level1",
        "TESTGRP": "SET"
}"""

class myLib(object):
    def change_test_details(self, ver, lvl, grp):
        d = json.loads(cmd)
        d["TESTVER"] = ver
        d["TESTLVL"] = lvl
        d["TESTGRP"] = grp
        print(json.dumps(d, indent=2))

This is my Robot script extract:

test Suite to be selected and executed ${TEST}
    Log to Console   ${TEST}
    Change test details    "v1", "L1", "Get"

I keep getting " No keyword with name 'Change test details' found. " - how can I pass multiple param from Robot to Python scripts?

class myLib(object):
    def change_test_details(self, ver, lvl, grp,filename):
        d = json.loads(cmd)
        d["TESTVER"] = ver
        d["TESTLVL"] = lvl
        d["TESTGRP"] = grp
        with open(filename, 'w') as outfile:
            json.dump(d, outfile,indent=2)
        return 'Done'
x=myLib()
ver=1
lvl=1
grp=1
filename =r'file.json'
v=x.change_test_details(ver, lvl, grp,filename)
print(v)
"""
output

done
