I’m getting an error "Term Ends At: Should be in valid date format"
While performing any time-related changes via APIs, we need to ensure that the time format is in timestamp (UTC) in seconds. Normally, you can use any online converter to convert time format into timestamps (UTC) in seconds.
There are multiple time converter apps such as epoch, on which you can convert date, month, year, and time to timestamp and vice versa. Note, that it should NOT be in milliseconds, screenshot for reference.
