I am having serious issues trying to sync dates. SN has a field called due_date that we are trying to sync to due date in Jira.   I am getting a cannot cast object error.

Error Detail Message:

Cannot cast object '01/03/2022 16:20:59' with class 'java.lang.String' to class 'java.util.Date'

Error line: 34

    This was originally raised via support but I was asked to post here: 

    The error you are receiving seems to be a configuration problem we use a community site at community.exalate.com to discuss the configuration of the synchronization.

    Kindly raise the question there, we will be responding shortly, the advantage is that other people can benefit from the effort.

    i have the same with issue.created=replica.created. From Zendesk to Jira Cloud

    Hi Robert Horan 

    What the error is stating is that the object being tried to pass to into the field is a String, while the field is expecting a Date format data, you can make this conversion the following way:


    Hope this is helpful,

    Hi Daniel, 

    I have that document but it didn't help.  I don't know enough about this tool to make that work.  What needs to be added to the incoming/outgoing sync for ServiceNow?  Jira?

    According to https://docs.idalko.com/exalate/display/ED/How+to+synchronize+a+Due+Date+field+in+Jira+Cloud 

    Outgoing sync

    To send the Due date use the code below  

    replica.due = issue.due

    Incoming sync

    To apply the received Due Date value on your side add the code below

    issue.due = replica.due

    It's not clear to me how or even where this fits in.  There could be multiple date fields, not to mention date and time fields.

    Hi Robert Horan 

    The code mentioned in the document can be set at the beginning of your Jira's Incoming Script(line 1) since what its gonna do is format the date to the expected data type.

    We can see that the date format being received is a bit different from the one shown in the documentation example, the error shows the format as: '01/03/2022 16:20:59', therefore we need to change the datePattern to match the received value:


    def datePattern = "yyyy-MM-dd HH:mm:ss.S"


    def datePattern = "dd-MM-yyyy HH:mm:ss.S"

    Then we add the variable that actually contains the date which is the "replica.due" to the parser: 

    import java.text.SimpleDateFormat;
    import java.text.DateFormat;
    // define the desired date/time format
    def datePattern = "dd-MM-yyyy HH:mm:ss.S";
            DateFormat formatter = new SimpleDateFormat(datePattern);
            date = formatter.parse(replica.due);

    And then we can take the created variable that contains the formatted date and use it to fill the issue.due, this part can go anywhere as long as its after the code above:

    issue.due = date

    Since you mentioned there can be multiple date fields you can reuse the parser simply by changing the replica being applied so, let's say you are sending from SNOW the following fields:

    replica.due = issue.due
    replica.veryDue = issue.veryDue
    replica.reallyDueNow = issue.reallyDueNow

    then in Jira incoming you could have them as:

    date = formatter.parse(replica.due);
    dateVeryDue = formatter.parse(replica.veryDue);
    dateReallyDueNow = formatter.parse(replica.reallyDueNow);
    issue.due = date
    issue.veryDue = dateVeryDue
    issue.reallyDueNow = dateReallyDueNow

    So as you can see you can use the parser in your code as needed with that structure:

    "variableName = formatter.parse(replica.ContainingTheTimeOrDate);"

    I hope this information is helpful.
