PATTERN_NOT_MATCHED when scheduling email using API

Hi,

Right now, I am trying to schedule an email using the API. While options 1-5 work, whenever I try option 6 (custom time) and provide a datetime in the requested format, I simply get this as an error:

{
    "data": {
        "errorCode": "PATTERN_NOT_MATCHED",
        "moreInfo": "zoho-inputstream Input does not match the given pattern"
    },
    "status": {
        "code": 400,
        "description": "Invalid Input"
    }
}

I know that the "scheduleTime" parameter is causing the issue as changing the scheduleType to any number from 1-5

and clearing the "scheduleTime" parameter works perfectly.

Here's my request information:

URL: https://mail.zoho.com/api/accounts/<account_id>/messages

Method: POST

Request Body (JSON):

{
   "fromAddress": "example@mail.com",
   "toAddress": "example@mail.com",
   "subject": "Email - Always and Forever",
   "content": "Email can never be dead. The most neutral and effective way, that can be used for one to many and two way communication.",
   "isSchedule": true,
   "scheduleType": 1,
   "timeZone": "America/Toronto",
   "scheduleTime": "01/05/2022 11:11"
}
Please let me know how I can fix this.

Thanks.
