Hi

I trying to retrieve some text from the follow website.
https://ssd.jpl.nasa.gov/horizons_batch.cgi?batch=1&TABLE_TYPE=OBSERVER&QUANTITIES=%274%27&COMMAND=%224%22&SOLAR_ELONG=%220%2C180%22&LHA_CUTOFF=0&CSV_FORMAT=YES&CAL_FORMAT=BOTH&ANG_FORMAT=DEG&APPARENT=AIRLESS&REF_SYSTEM=J2000&EXTRA_PREC=NO&CENTER=coord%40399&COORD_TYPE=GEODETIC&SITE_COORD=%27-63.131100%2C46.238200%2C0.060000%27

I set up the the following Json_path = [0, 'text']
and issuing command : magtag.fetch()
gets the following errors

Code: Select all | TOGGLE FULL SIZE

Retrieving data...Traceback (most recent call last):
  File "code.py", line 27, in <module>

  File "adafruit_requests.py", line 551, in request
  File "adafruit_requests.py", line 546, in request
AttributeError: 'NoneType' object has no attribute 'split'

Any ideas how I can work around the problem?
Is there a way I can use the fetch command just to download raw bytes

Thanks for the help.

The first step is usually to make sure you are using the latest libraries. We tend to fix bugs pretty quickly.

I don't think there is an easy work around. Requests is usually as low as you want to go because it handles HTTP.

I got a good response from using:

response=magtag.network.requests.get(url)

Possible issue with the fetch command is it nor expecting null characters in the response.

I updated my libraries to current version and now have a rat nest of dependancy issues (new Post) and I am dead in the water until resolved as I did not save the old version before testing

Anywhere to find old library versions

Thanks for the help.
