ClassCastException

{code}String customerValue = epic.getCustomFieldValue(customerField);
String frrNumberValue = epic.getCustomFieldValue(frrNumberField);

//First Set the value of PFRR i.e customer & FRR number from the above string
if(customerValue!= null)
{
System.out.println("@@@@@@ Customer Value " +customerValue)
Options options = ComponentAccessor.getOptionsManager().getOptions(customerField.getConfigurationSchemes().listIterator().next().getOneAndOnlyConfig());
def optionToSelect = options.find { it.value == customerValue};
myIssue.setCustomFieldValue(customerField, optionToSelect.getOptionId().toString());
ComponentAccessor.getIssueManager().updateIssue(appUser, myIssue, EventDispatchOption.DO_NOT_DISPATCH, false);
System.out.println("@@@@@@ Issue Key " +myIssue.getKey());

}{code}

I tried with this code but getting the below error

What's the type of your customField (is it a select drop-down?), as from your code the first line itself looks incorrect.

You have written

String customerValue = epic.getCustomFieldValue(customerField);

In the above code statement epic.getCustomFieldValue will return an type "Option" if the field is of type "select drop down" and you are trying to map it to an String and thus you see an Exception.

Thanks for your response.

I have resolved that issue...the scenario is we want to update all the issues that are there in out instance with specific type with the two fields.

if i update some stuff of code on that create issue transition as post function then it is updating that particular custom fields values but we want all the issues which is created in epic and linked issue of that particular issue type
