Im trying like this, but it is not working:

ticker_list = list(tickerStrings)  # Your ticker list   
max_items = 100   
results = []
   
for i in range(0, len(ticker_list), max_items):       
try:           
chunk = ticker_list[i:i + max_items]           
df_chunk = ld.content.pricing.Definition(               
chunk,               
fields=['CF_LAST', 'CF_CLOSE']           
).get_data().data.df           
results.append(df_chunk)       
except Exception as e:           
print(f"Error processing chunk {i//max_items + 1}: {e}")

output:

No user scope for key=/data/pricing/snapshots/v1/, method=GET.

ps: im not using config file to connect. im connecting calling this function:

def ld_connect(APP_KEY = os.environ['REFINITIV_EDP_API'], USER = os.environ['REFINITIV_USER'], PASS = os.environ['REFINITIV_PASSWORD']):    session = ld.session.platform.Definition(        app_key = APP_KEY,        grant = ld.session.platform.GrantPassword(            username = USER,            password = PASS        ),        signon_control = True    ).get_session()    session.open()    ld.session.set_default(session)    print("LSEG connected")    return session

ld_connect()
