Getting error while calling the Leave Booked and Balance Report API

Hi,

I get the following error

{"error":{"code":7213,"message":"The provided OAuth token is invalid."},"uri":"/api/v2/leavetracker/reports/bookedAndBalance"}

The OAuth token is valid as I am using it in other APIs. Can you please let me know why this error occurred?

dat = Map();

dat.put("recordId","67512000000410165");

dat.put("from","01-Jan-2022");

dat.put("to","31-Jan-2022");

dat.put("unit","Day");
