Issues observed in " karate-junit5 " library when migrated from version 1.2.0 to 1.3.1 - karate

Question

Recently I upgraded the version of karate-junit5 library from 1.2.0 to 1.3.1.
I have a common feature file which contains some common functions used all other scenarios like below sample.
common.feature
#Common
Scenario: Common scenario
* def someFunction =
"""
function(){
karate.log('In some function..');
var textArray = driver.locateAll("//*[#role='button']").map( x => x.text)
karate.log('Button text is: ', textArray);
}
"""
* def getDateInFormat =
"""
function(date){
var curr_date = date.getDate();
if(curr_date < 10)
curr_date = '0' + curr_date;
var curr_month = date.getMonth() + 1;
if(curr_month < 10)
curr_month = '0' + curr_month;
var curr_year = date.getFullYear();
var mod_date = curr_date + '/' + curr_month + '/' + curr_year;
return mod_date;
}
"""
* def sortFunction =
"""
function(sortArr, sortType){
if(sortType == 'asc')
sortArr.sort();
else
sortArr.reverse();
return sortArr;
}
"""
I call above common scenarios from other feature files whenever required. A sample calling feature file would be as below.
Test.feature
Feature: Test feature
Background:
* callonce read('common.feature#Common')
Scenario: Test 1
* print "Today's date is: ", getDateInFormat(new Date())
Scenario: Test 2
* print "Sorted data by A to Z is: ", sortFunction(['Dog', 'Cat', 'Horse'], 'asc')
Scenario: Test 3
* configure driver = { type: 'chrome', addOptions: ['--ignore-certificate-errors', '--incognito', '--disable-gpu', '--window-size=1920,1080', '--no-sandbox'], headless: false }
* configure retry = { count: 10, interval: 2000 }
* driver 'https://www.google.com/'
* someFunction()
All the scenarios 1,2 and 3 are executed properly for 1.2.0 version but throw below errors for when library version is upgraded to 1.3.1 :
For Scenario 1:
" org.graalvm.polyglot.PolyglotException: TypeError: invokeMember (getDate) on java.util.LinkedHashMap#6a969fb8 failed due to: Unknown identifier: getDate "
For Scenario 2:
" org.graalvm.polyglot.PolyglotException: TypeError: invokeMember (sort) on java.util.ArrayList#ff6077 failed due to: Arity error - expected: 1 actual: 0 "
For Scenario 3:
" org.graalvm.polyglot.PolyglotException: ReferenceError: "driver" is not defined "
Can somebody explain what has changed in karate-junit5 library version 1.3.1 from 1.2.0 ?
For Scenario 2, sortArr.reverse() is working properly even in 1.3.1 karate version. Above error is observed for sortArr.sort().
For Scenario 3, if I change the someFunction() to accept driver , like someFunction(driver), then it is executed properly on 1.3.1 version as well.
