'GSERFCI INDEX' cause problem

[lastrocer]

I can replace 'GSERFCI INDEX' with 'not a ticker' the program run fine but if I use 'GSERFCI INDEX'. code doesn't run poperly.
no df_out and problem_tickers='index' . There are several "name" cause the problem this is one of them.

Can you help? thank you.

con = pdblp.BCon()
con.start()
tickers = [['C US Equity','SPY US Equity','IBM US Equity', 'S5INSS INDEX', 'GSERFCI INDEX']]
df_out = pd.DataFrame()
L = []
for i in tickers:
try:
df = con.ref(i, ["PX_LAST"])
df_out = df_out.append(df)
except Exception as e:
problem_ticker = e.args[0].split()[-1]
L.append(problem_ticker)
problem_tickers = pd.DataFrame(L, columns=['TICKER'])

You probably want to set con.debug = True and look at the output for indications of the possible issue.
