Refinitiv Python Connection Open session HTTTP Request id 0; get_date failed

Hi @Tim Lai, then I'm afraid it's something to do with the trigger. I tested it on my end and the following worked via Task Scheduler prompts:

import lseg.data as ld
import time
import logging

print('imports worked')

time.sleep(1)

path = "C://Users//john//Desktop//Desktop//"

# Configure logging
logging.basicConfig(
    filename=path + 'error_log.txt',
    level=logging.ERROR,
    format='%(asctime)s:%(levelname)s:%(message)s')

print('Configuration worked')

time.sleep(1)

ld.open_session()

print('ld.open_session worked')

time.sleep(1)

df = ld.get_history('LSEG.L')

print(df.iloc[0])

time.sleep(1)

# Save DataFrame to a text file
df.to_csv(
    path_or_buf=path + "LD_printout_via_task_scheduler_test.csv",
    # sep='\t',
    index=False)

print("DataFrame has been written to LD_printout_via_task_scheduler_test.txt")

time.sleep(1)

ld.close_session()

Looking at the output in the screenshot you shared above, I can tell that the app key used is incorrect. You can find information on how you can find your app key here: Quick Start | Devportal (lseg.com)

In your code, please use a line like:

ld.open_session(
    config_name="C:\Example.DataLibrary.Python-main\Configuration\lseg-data.config2.json",
    name="desktop.workspace")

and point to your json configuration file directly; it does look like the default is not the one where you entered your app key, but instead it is one where the app key 'DEFAULT_WORKSPACE_APP_KEY' is written, which cannot be the correct app key.
