If someone has faced this and come up with a workaround, I would like to know, please. The code is M&M for Mahindra and Mahindra, and the links for the same are as follows:

The last works for me:

gnc-fq-dump yahoo_json 'M%26M.NS'
Finance::Quote fields Gnucash uses:
    symbol: M%26M.NS             <=== required
      date: 08/14/2020           <=== recommended
  currency: INR                  <=== required
      last: 614.45               <=\
       nav:                      <=== one of these
     price:                      <=/
  timezone:                      <=== optional

and
echo '(yahoo_json  "M%26M.NS")' | gnc-fq-helper
(("M%26M.NS" (symbol . "M%26M.NS") (gnc:time-no-zone . "2020-08-14 12:00:00") (last . #e614.45) (currency . "INR")))

I tried it in GnuCash. Worked there too.
