Exception Doesn't Catch Connection Issues

[beaconIOT]

Sorry if this is answered somewhere else, I've tried looking through all the issues/support documentation but can't find the answer or what I'm doing wrong. I'm just trying to handle connection/HTTP errors in my Pyrebase calls in my code but I can't get it to catch the exception. When I test (by turning wifi off on the rPi, it just hangs indefinitely. Below is the code I'm trying to catch the exception with: (and yes, I am also using import requests )

try: database.child(deviceID).child(path).set(value) except requests.exceptions.HTTPError as e: response = e.args[0].response error = response.json()['error']

You need to capture the exception and load the text response to json:

`try:

except Exception as e: json_data = json.loads(e.args print(json_data['error']['message']` Hope this helps!

@JustinHBird Thanks Justin- I'm going to give this a go right now!

@JustinHBird I just gave that a go but still having issues with the code freezing when I turn off wifi. First, I changed the syntax of your code to be:

try:                
      database.child(deviceID).child(path).set(value)
except Exception as e: 
      json_data = json.loads(e.args)
     print(json_data['error']['message'])

And what I get now is code freezing right when the wifi get's turned off and then if I hit Ctrl+C it shows the following. Any advice would be amazing!

[code is running fine here then wifi turns off]

It's hard to tell without looking at the code.
