Python refinitiv lib token expiration error

Pedro_Novaes

I'm using refinitiv lib in python like this:

import refinitiv.data as rd
rd.get_data(universe=self._stocks,fields=["TR.HIGHPrice","TR.OPENPrice",
"TR.CLOSEPrice","TR.LOWPrice","TR.CLOSEPRICE.DATE","TR.ACCUMULATEDVOLUME",
"TR.NUMBEROFBLOCKTRADES","TR.TSVWAP"],
parameters={'SDate':self._start.strftime("%Y-%m-%d"), 'EDate':self._end.strftime("%Y-%m-%d")}
)

In a loop that gets data for multiple RICs, after a certain time I start getting this error:
Error code -1 | token expired

The lib never asks me for a token, so I don't know how to deal with this error

Hello @Pedro_Novaes

Thank you for reaching out to us. Please make sure that the RDP account is not used by other users or applications while running the application because there is only one active session for each RDP account.

For example, if the same RDP account is used by another user or application, the previous session will be invalidated and the previous application can't renew the token.

If you want to run multiple applications/sessions, I highly recommend you reach out to your LSEG representative to get multiple RDP accounts.

Alternatively, you may set the "signon_control" in the refinitiv-data.config.json to true. This parameter overrides any previous session you logged on i.e. force sign-out this ID from other applications and sign-in here.

            },

            "file": {

                "enabled": false,

                "name": "refinitiv-data-lib.log"

            }

        }

        "platform": {

            "rdp": {

                "app-key": "YOUR APP KEY GOES HERE!",

                "username": "YOUR RDP LOGIN OR MACHINE GOES HERE!",

                "password": "YOUR RDP PASSWORD GOES HERE!",

  		      "signon_control": true

            }

        }


    }

}

You can enable logging in the library to verify what the problem is and then share log files when the problem occurred. Please also remove the RDP credentials in the log file.
