Hi guys,

Initially I kept getting some weird errors about missing midnight property when running the code, but then found that it's actually due to this specific line throwing MemoryError (but swallowed by except)

Adafruit_Learning_System_Guides/Matrix_Portal_Moon_Clock/code.py

Line 149 in 9547afe

full_data = json.loads(NETWORK.fetch_data(url))

It seems that converting json from the response string takes quite a memory:

                full_data = json.loads(NETWORK.fetch_data(url))
                moon_data = full_data['location']['time'][0]

After going through the code, I noticed there is an overload that will enable fetching specific path and return the result in needed json/dictionary object, so simple code change below will solve the problem

                location_data = NETWORK.fetch_data(url, json_path=[["location"]])
                moon_data = location_data["time"][0]

Hope this helps someone who's getting the same problem as mine
Thanks.

fixed in latest pr
