Unable to establish OMMStreamConnection while calling ld.get_data

AbdullahMuhammad

I’m getting an error while fetching Qatar Stock Exchange data using the LSEG Python SDK.

import lseg.data as ld
session = ld.open_session(    config_name='config.json')
df = ld.get_data(    universe=['QNBK.QA'],    fields=['TRDPRC_1'])

Error:

lseg.data._errors.LDError: Cannot prepare connection OMMStreamConnection
name : ThreadOMMSTREAMING_PRICING_0.0
state : StreamCxnState.Disposed
subprotocol : tr_json2
is_auto_reconnect: True
can_reconnect : False

Thank you for reaching out to us.

The log indicates that the library was unable to establish a streaming connect to retrieve data.

Please enable the debug log in the library by using the following configurations.

{   
       
    "logs": {
        "level": "debug",
        "transports": {
            "console": {
                "enabled": false
            },
            "file": {
                "enabled": true,
                "name": "lseg-data-lib.log"
            }
        }
    },
…

}

With these configurations, the lseg-data-lib.log file will be created. Please share the log file when the problem occurred.
