Hi @theo.px ,

Without more detail, and especially without log file, it isn' t obvious to find a cause.

You should search for log related to subscription id 4 (initial open request, status, error and/or refresh response, ...)

If you installed and updated eikon lib with different version, you can reinstall with "pip install --upgrade --force-reinstall eikon" to be sure that you have all dependencies with the right version.

I don't know where to find the logs, here is my code :

import eikon as ek
import datetime

ek.set_app_key('XXX')
streaming_prices = ek.StreamingPrices(

    instruments = ['GBP=','JPY=', 'CAD='],

    fields   = ['CF_BID','CF_ASK','OPEN_PRC', 'CF_HIGH','CF_LOW', 'CF_CLOSE']

)

streaming_prices.open()

df = streaming_prices.get_snapshot(
        instruments = ['JPY=', 'CAD='],
        fields = ['CF_BID','CF_ASK']
)
print(df)

What more do you need ?

The code is sending me the ID4 message at line 15.

PS : I can't seem to be able to upload any image I've got a "Parsing response failed" error

You can activate debug traces with this way:

ek.set_app_key('XXX')
ek.set_log_level(1)
...

Then, you'll have a pyeikon.yyyymmdd.hh-mm-ss.log file in same directory than your script. You should also have traces in your console window.

One possibility that could cause your issue: for some rics, subscription can switch to delayed (ex: subscription to "EUR=" => switched to "/EUR=" ).

Currently, Python API doesn't support this.

I can't upload files either.

Here is the logs :

This log explains the reason why the web socket can't be opened:

Receive message for login 4: {'ID': 4, 'State': {'Code': 'ConnectionError', 'Data': 'Suspect', 'Stream': 'Closed', 'Text': 'Cannot establish connection to the platform'}, 'Type': 'Status'}

This status message is returned by the Eikon Desktop Proxy.

If you activate debug logs in Eikon Configuration Manager then explore Log folder (it should be C:\ProgramData\Thomson Reuters\Eikon Data\Logs but to be sure, open it from Eikon Configuration Manager application) and check APIProxy.yymmdd.hhmmssmmm.p<pid>.txt file in \TRD\Eikon.yyyymmdd.hhmmss.pXXXXX subfolder.

You should fin message related to /api/rdp/streaming/pricing/v1/WebSocket.
On my side (without error):

Hello,

So I launched the Eikon Configuration Manager application (in edition mode),I activated the logs by ticking the "Configure Logs on the Workstation" box. I then clicked on "Open logs folder" and in \TRD\Eikon.yyyymmdd.hhmmss.pXXXXX subfolders I don't have any log files that looks like APIProxy.yymmdd.hhmmssmmm.p<pid>.txt . So I opened the Logs viewer in the Eikon Configuration Manager application and the only log appearing (every 20s) is

10:09:25 Condition 'Configuration:RDE_SSO_CONNECTION_STATUS' == 'ONLINE' is false 
10:09:25 Device 'PROFILE-UPLOAD' does not upload its data because condition is false 

I don't know if it has to do with the API !

Thank you in advance for your help

I didn't catch you're using Refinitiv Workspace !
The log file you should check is node-sxs.yyyymmdd.pXXXX.log, but it'll be less easy because it contains traces from SXS and APIPROXY.

Search messages related to APIPROXY and WebSocketServer.
These messages are related to local web sockets available for python clients:

If there is error with the web socket between this APIPROXY and the platform, it should be logged.
