I'm trying to process the streaming data from RDP in Python receiving updates on multiple RICs. It seems to me that the only class from the https://pypi.org/project/refinitiv-dataplatform/ library that can handle multiple RICs is StreamingPrices(). Unfortunately when I'm running my code below, I don't receive any data.

streaming_prices = rdp.StreamingPrices(
    universe=['EUR='],
    fields=['BID', 'ASK'],
    on_update=lambda streaming_price, instrument_name, f:
print("Update received for {}: {}".format(instrument_name, f))
)

streaming_prices.open()
while True: time.sleep(0.2)

The log looks as follows:

2020-02-28 09:44:28,347 Login to websocket successful

2020-02-28 09:44:48,347 Receive ping from server ...

2020-02-28 09:44:48,348 ... send pong response

2020-02-28 09:45:08,346 Receive ping from server ...

2020-02-28 09:45:08,346 ... send pong response

...

On the other hand, when I use the ItemStream() class with the following code, it works perfectly. But ItemStream() cannot handle multiple RICs, so it's not a solution to my problem.

streaming_prices = rdp.ItemStream(
    session=rdp.get_default_session(),
    name='EUR=',
    fields=['BID', 'ASK'],
    on_update=lambda s, msg:
    print("Update received: {}".format(msg)))
streaming_prices.open()
while True: time.sleep(0.2)

The log looks the same, but I can see the updates being printed in the console:
