Steps to Reproduce
Run Robyn with an endpoint that return a datetime:
- Create
app.py:
from robyn import Robyn
from robyn.types import JSONResponse
import datetime
app = Robyn(__file__)
@app.post("/test_1")
def test_1() -> datetime.datetime:
return datetime.datetime.now()
if __name__ == "__main__":
app.start(host="0.0.0.0", port=8080)- Run it:
python app.py
It also poses a problem with datetime.date or with a JSONResponse object encapsulating the field:
@app.post("/test_2")
def test_2() -> datetime.date:
return datetime.date.today()
class DateObject(JSONResponse):
date: datetime.datetime
@app.post("/test_3")
def test_3() -> DateObject:
return DateObject(date=datetime.datetime.now())Your operating system
