Groovy function to use conditional operator and datetime parsing - date

Question

I want to write a groovy function in the "transformConfigs" of table config, in Apache Pinot. I want to assign value 'A' if my timestamp is greater than 7:00:00, but otherwise assign value 'B' in the column.
These are what I have tried, but none of these work:
Groovy({LocalDateTime.parse(t, \"yyyy-MM-dd hh:mm:ss.SSS\").toDate().format('HH:mm:ss') > LocalTime.of(7, 0, 0) ? 'A' : 'B'}, t)
Groovy({java.time.format.DateTimeFormatter.LocalDateTime.parse(t, "yyyy-MM-dd hh:mm:ss.SSS").toDate().format('HH:mm:ss') > java.time.format.DateTimeFormatter.LocalTime.of(7, 0, 0) ? 'A' : 'B'}, t)
Groovy({SimpleDateFormat time_now = new SimpleDateFormat(\"yyyy-MM-dd hh:mm:ss.SSS\"); SimpleDateFormat output = new SimpleDateFormat(\"hh:mm:ss.SSS\"); Date d = time_now.parse(t); String f_time_now = output.format(d); String f_shift_time = output.format(\"07:00:00.000\"); def result = formattedTime > f_shift_time ? 'A' : 'B'; return result}, t)

}
]
},
"isDimTable": false
}
}

}
Output: no ingestion takes place.
Thank you in advance. Let me know if I can provide more details.
