Error with websocket API connection to https://api.refinitiv.com/streaming/pricing/v1/

I am running the following example code: https://github.com/Refinitiv/websocket-api/blob/master/Applications/Examples/RTO/python/market_price_rto_service_discovery.py as follows: ``` python3 market_price_rto_service_discovery.py --user "" --password "" --clientid ""

The output is: ``` Sending authentication request with password to https://api.refinitiv.com:443/auth/oauth2/v1/token ... LSEG Delivery Platform Authentication succeeded.

I tried adding the `--ric "GBP=X"` argument and received the same error. Technical support noticed that the service discovery process had determined that a small ("sm") endpoint should be used. I edited the script to hard-code it to use "us-east-1-aws-3-lrg.optimized-pricing-api.refinitiv.net", and login failed with the following message:

"Login Rejected. Watchlist size of 0 for 'WS JSON2' connection is outside of range [20001,50000] supported for this ADS fanout tier for this type of connection."

When I hard-code it to use "us-east-1-aws-3-med.optimized-pricing-api.refinitiv.net", I get a completely different error:

Sending authentication request with password to https://api.refinitiv.com:443/auth/oauth2/v1/token ... LSEG Delivery Platform Authentication succeeded.

We use these credentials successfully to connect using the Java SDK. How can I establish a connection to the websocket API using this account?

Watchlist size of 0 implies that it is an account permissioning issue (improperly configured). Please raise it up with the account manager.
