Kite.quote throws error when I send a list of instruments but works when I iterate through the list.

healthsecure15
Hi,

Number of instruments: 498, these are in a list.

When I do:
try:
kite.quote(list_of_instruments)
except Exception as e:
print(e)
kiteconnect.exceptions.DataException: Unknown Content-Type (text/html) with response: (b'

400 Bad request

\nYour browser sent an invalid request.\n\n')
If I do:
count = 0
for i in list_of_instruments:
try:
z = kite.quote(i)
count+=1
print(count)
except Exception as e:
print(e)
print(f'\n\n\n{i}')
No error.

If I understand correctly upto 500 instruments can be requested in a list. Please let me know what the error is about.

TIA

    Are you sure, you are passing kite.quote(list_of_instruments) list here of instruments in proper string format with proper comma separator?
    Eg: list_of_instruments = ["NSE:SBIN", "BSE:ONGC", ....]

    @rakeshr strange when I reduce the number of instruments to 400 in 1 list. It has no issues. I think I read in the documentation that upto 500 instruments at a time is not an issue. Please clarify?

    @healthsecure15,
    It could be because length of param is too long. You can try using only instrument tokens that will reduce the payload length.
