Data type - REST API

I am using REST API add-on to execute a service method and have some questions on date date type.

I am sending DateTime parameter value from Flutter and in my REST API Backend, using java.util.Date parameters. However, when I read the exception below it looks like there are some extra characters received by the REST API as below.

astSecurityFilter - REST API request [***xcNE] GET

Here is the Server siide codes:

REST Service:

<method name="createLeaveApplication">
        <param name="employeeCode" type="java.lang.String"/>
        <param name="leaveType" type="java.lang.String"/>
        <param name="startDate" type="java.util.Date"/>
        <param name="endDate" type="java.util.Date"/>
        <param name="durType" type="java.lang.String"/>
        <param name="note" type="java.lang.String"/>


    public void createLeaveApplication(String employeeCode, String leaveTypeCode, Date startDate, Date endDate, String durType, String note){

Thanks for any help suggesting a fix.

Hi Mortoza,

First, your parameter names do not match: leaveType in registered service method, leaveTypeCode in the request.

Second, you should use the ISO format for passing date/time values, for example 2022-04-12T18:56:32.

Thank you Konstantin.
LeaveType/LeaveTypeCode - I was doing so many ways to try, I copied it from wrong place…Thanks for mentionting.

I’ll try using ISO date format as suggested. From REST API, which date format should I use,

Another related question, what is the data type we should use for saving images from a client app to REST backend? The image data field in the Entity is ByteArray but there is no such data type in JSON.

Hi @krivopustov, I still facing that error: DateTimaParseException: Text '2022-03-29' could not be parsed at index 10. I’ve tried this patterns: yyyy-MM-ddTHH:mm:ss, yyyy-MM-dd HH:mm:ss.SSS and yyyy-MM-dd, they too throws this error. Could you please suggest patterns for @Temporal(TemporalType.DATE). and

Hi @maihanov96
Please provide your service method signature and its configuration in rest-services.xml.
