getOptionChain stopped working

mif2000 commented 5 months ago

Description

I use vba and Excel as interface to the BERT UI for R-based support of end-user inquiries to Yahoo finance. I've been doing this for 1-2 years, but know very little about the "system" side of BERT. A few days ago getOptionChain stopped working.

Expected behavior

Until recently an R call such as: Expirations <- getOptionChain("AAPL", NULL)

would provide a list of expiries, from which I could choose one and (after manipulating the date a bit) optionChain <- getOptionChain("AAPL", expiry)

to provide an xts chain with calls and puts tables.. Now these getOptionChain calls return: Warning: no data for "AAPL expiry, omitting (server response: HTTP error 401.) and/or Error in Exp/86400: non-numeric argument to binary operator, which seems to indicate a Yahoo authorization error.

Minimal, reproducible example

Expirations <- getOptionChain("AAPL", NULL)
