Server Error when accessing the example HTTP server

[richardklingler]

When I want to access the example http ruuvi server running a raspberry pi 3b I get a server error 500 as soon I want to access either /data or /data/MAC:

• Serving Flask app "ruuvi" (lazy loading)
• Environment: production

Hi. Can you send me your server file (ruuvi.py).

File "ruuvi.py", line 50, in update_data
allData[key][0] = value
TypeError: tuple indices must be integers or slices, not str

It seems that it uses tuple instead of dictionary for some reason. Couldn't find same line from the default example implementation (https://github.com/ttu/ruuvitag-sensor/blob/master/examples/http_server.py).

Huomenta (o;

Well it is actually this file just with modified MAC addresses:

"""

app = Flask(__name__)

m = Manager()
q = m.Queue()

allData = {}

tags = {
    'EF:DE:E1:49:3C:9B': 'office',

    def callback(data):

        queue.put(data)

    RuuviTagSensor.get_datas(callback, macs)


def update_data():
    """

    global allData
    while not q.empty():
        allData = q.get()
    for key, value in tags.items():
        if key in allData:
            allData[key]['name'] = value


@app.route('/data')
def get_all_data():
    update_data()
    return json.dumps(allData)

    return json.dumps(allData[mac])


if __name__ == '__main__':
    # Start background process
    executor = ProcessPoolExecutor(1)
    executor.submit(run_get_data_background, list(tags.keys()), q)

    # Strt Flask application
    app.run(host='0.0.0.0', port=5000)

Just redownloaded it and changed the MAC addresses....still the same error:
