Tested by adding API keys getting unexpected error on every tick

2025-07-23 04:08:26,069 - hummingbot.connector.exchange.gate_io.gate_io_api_user_stream_data_source.GateIoAPIUserStreamDataSource - ERROR - Unexpected error while listening to user stream. Retrying after 5 seconds...

OSError: {'label': 'WSS_ERROR', 'message': 'Error received via websocket - empty currency pair list.'}

Note: Added API keys on hummingbot client and create v1/v2 strategy works ok

Steps to reproduce bug

1. Add the API keys on dashboard or fastify endpoint using

   # POST /accounts/add-credential/{account_name}/{connector_name}
   curl -X 'POST' \
     'http://localhost:8000/accounts/add-credential/master_account/gate_io' \
     -H 'accept: application/json' \
     -H 'Content-Type: application/json' \
     -u username:password \
     -d '{
     "gate_io_api_key": "add here",
     "gate_io_secret_key": "add here"
   }' | jq
   

2. Check logs of hummingbot-api
