AB2001 while fetching historical candle data

[PandaTrade]

payloadCandleReq={'symbol':"SBIN-EQ",
                  'symboltoken': '3045',
                  'interval':'THIRTY_MINUTE',
                  'fromdate': "2021-04-01 9:15",
                  'todate': "2021-04-15 3:30"}
payload_req=json.dumps(payloadCandleReq)
conn.request("POST", "/rest/secure/angelbroking/historical/v1/getCandleData", payload_req, headers)
res = conn.getresponse()
data = res.read()
print(data.decode("utf-8"))

Now with this i get the error-

{"message":"Internal Error","errorcode":"AB2001","status":false,"data":null}

What is wrong in this?

"interval": "ONE_MINUTE",
"fromdate":"2021-04-19 09:15",
