Epoch_to_datetime not working properly when installed

GSQL Queries
#1

I store the date and time in a vertex in the form of epoch time, and i wanted to change it to datetime before having to display it.

  ListAccum<DATETIME> @lst;
  start = {ev}; 
  result = SELECT e from start:e ACCUM e.@lst+=epoch_to_datetime(e.must_start_by),e.@lst+=epoch_to_datetime(e.must_end_by);
  PRINT result[result.@lst];

this works when the query is run in interpreted mode and displays the datetime format but when i install the query and run it, it still gives me epoch time.

output when ran in interpretted mode :

  {
    "result": [
      {
        "attributes": {
          "result.@lst": [
            "2022-06-11 02:30:00",
            "2022-06-11 06:30:00"
          ]
        },
        "v_id": "106505115-1-352868",
        "v_type": "event"
      }
    ]
  }

output when i run after installing the query:

  {
    "result": [
      {
        "attributes": {
          "result.@lst": [
            1654914600,
            1654929000
          ]
        },
        "v_id": "106505115-1-352868",
        "v_type": "event"
      }
    ]
  }

please help me fix this.
