This is just the login response - where is the response from your item request?

The issue is that there is no item response. There is only Ping/Pong message after what I provided above.

Was there a SENT message in your console? Has your request even been sent to the server? You haven't included the full capture. Here is what I get:

I don't see the request being sent to server - there is probably a bug in the your python code somewhere. Please recheck the code - maybe add debugging statements.

Snapshot works with 'Streaming':False set:) The "Streaming":false was cut/paste from Refinitiv how to example snippets. Anyway, happy that this is identified/resolved. Thank you for your help again.

Good that it works now.
Refinitiv examples show the JSON messages - where false is a correct directive. If you use Python dictionary, then Python False will have to be used.
json.dumps(mp_req_json)
The above statement converts the dictionary object into JSON string in the self.web_socket_app.send(json.dumps(mp_req_json)) statement.
