Class File Editor - io.cucumber.core_3.0.2

Hi,
I am trying to debug the code and when the control goes to the array assignment line, katalon is returning the error with source not found with io.cucumber.core_3.0.2.
Please refer the below highlighted array assignment value and attached snap with the error details.
Can you please suggest how to proceed further ?

Step Definition
def user_click_on_bulk_assignment_link() {
if(runIndicator4!=‘N’) {
int[] valstore
valstore = new int[4]
valstore[0] = 0
valstore[1] = 0
valstore[2] = 0
valstore[3] = 0
int intal = 0

for(int j=0; j < rows_count2; j++) {
List cols2 = rows_table2.get(j).findElements(By.tagName(‘td’))
int cols_count2 = cols2.size()
for (int colum2 = 0; colum2 < cols_count2; colum2++) {
if(colum2==5) {
valstore[intal] = cols2.get(colum2).getText()
String celltext2 = cols2.get(colum2).getText()
intal = intal + 1
}
}
}

Any update on this?
