Exception thrown with simple Siphon ACIS Request

I'm using the following code in Google Colab with siphon 0.9:

from siphon.simplewebservice import acis
import json
params = {"sid":"KPIH","elems":"maxt,mint,avgt,pcpn,snow,snwd"}
ds = acis.acis_request("StnData", params)

Resulting error:

JSONDecodeError: Expecting value: line 1 column 1 (char 0)

During handling of the above exception, another exception occurred:

AcisApiException                          Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/siphon/simplewebservice/acis.py in acis_request(method, params)
     60         raise AcisApiException('Bad URL. Check your ACIS connection method string.')
     61     except ValueError:
---> 62         raise AcisApiException('No data returned! The ACIS parameter dictionary'
     63                                'may be incorrectly formatted')
     64 

AcisApiException: No data returned! The ACIS parameter dictionarymay be incorrectly formatted

Using Jupyter Lab resulted in the same error.

Fixed the issue by adding the start and end date to the query.

params = {"sid":"KPIH","elems":"maxt,mint,avgt,pcpn,snow,snwd","sdate":"por","edate":"por"}
