Trouble running command "python oledNewsFlash.py" for project News Flash Headlines

Orrin Woodard

i'm having trouble running the command "python oledNewsFlash.py" for project News Flash Headlines; it keeps giving me this return when I enter the command.

how do I fix this?

@Orrin-Woodard
Hopefully you have already replaced "your api key here" with "your valid API key" so your config.json should look like this
cat config.json

root@Omega-5A0F:~/oled-news-flash# cat config.json
{
    "X-API-KEY" : "your valid API key",
    "source" : "reuters",
    "sortBy" : "latest"
}

Probably the "source" : ... line is empty or not valid (valid news sources for example "reuters" or "cnn" or "hacker-news" ...).

vi is the default editor on Omega2(+). You may install for example nano if vi is too strange for you:
opkg update
opkg install nano
nano config.json

Edit the file, Write Out (save it) with Ctrl+o hit Enter and Exit with Ctrl+x.
Check it again with cat config.json

Or you might use the web based Onion Console's Editor App
Onion Omega2 Documentation Developing using the Console

Good luck!

It's time to start software testing, troubleshooting, debugging...
Do it yourself or do ask the author (James Liu) or one of Onion Omega2 Project Book Vol. 1 software experts:

My previous 'config.json' idea (guess) was wrong.
This error occurs if the program get some response without 'author' and/or 'publishedAt' (date):

Unfortunately I haven't got any OLED Expansion so I can't completely test this oledNewsFlash.py masterpiece.

This is the original oledNewsFlash.py by thepiper (James Liu)
I've made some simple modifications. download

Against urllib3 SSL Warnings

/usr/lib/python2.7/site-packages/urllib3/connectionpool.py:843: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised.

urllib3.disable_warnings()

Against 'author': None and/or 'publishedAt': None

Traceback (most recent call last):
  File "oledNewsFlash.py", line 81, in <module>
    latest['author']
  File "oledNewsFlash.py", line 18, in WriteHeadline
    oledExp.write(author)
TypeError: argument 1 must be string, not None


    # writes the authors at the bottom - might overflow back to page 0
    if author == None:
        author = "author n/a"


    # writes timestamp at the end to ensure it doesn't get overwritten
    if time == None:
        time = "timestamp n/a"

It's very frequent on "hacker-news"

Against "sortBy" : "latest"

Traceback (most recent call last):
  File "oledNewsFlash.py", line 72, in <module>
    latest = newsJson['articles'][0]
KeyError: 'articles'

On certain "source" : "bbc-news" ("cnn", "google-news", ...) you should use the "sortBy" : "top" parameter instead of "sortBy" : "latest".

config.json

{
    "X-API-KEY" : "your valid API key",
    "source" : "cnn",
    "sortBy" : "top"
}

I haven't got any Oled Expansion - so any feedback would be nice.

Thank you,
gf.
