:ssl.connect() always returns :socket_options error!
Hi!
What is the right way of calling the :ssl.connect() ? From Examples — OTP 29.0.2 (ssl 11.7.2) it looks like it should be:
:ssl.start()
:ssl.connect("google.com", 443, [{:verify, :verify_peer},{:cacerts, :public_key.cacerts_get()}])
But no matter what host or options I try, I get the same:
Interactive Elixir (1.14.4) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> :ssl.start()
:ok
iex(2)> :ssl.connect("google.com", 443, [{:verify, :verify_peer}, {:cacerts, :public_key.cacerts_get()} ])
{:error,
{:options,
{:socket_options,
[packet_size: 0, packet: 0, header: 0, active: false, mode: :binary]}}}
Does anyone know what am I doing wrong?
Thanks!

Since :ssl is an erlang lib I expect you would need to put the URL in single quotes for Elixir, like 'google.com'. That may not be the source of the error you are seeing but it might help.

Yup
iex(3)> :ssl.connect("google.com", 443, [{:verify, :verify_peer},{:cacerts, :public_key.cacerts_get()}])
{:error,
{:options,
{:socket_options,
[packet_size: 0, packet: 0, header: 0, active: false, mode: :binary]}}}
iex(4)> :ssl.connect('google.com', 443, [{:verify, :verify_peer},{:cacerts, :public_key.cacerts_get()}])
{:ok,
{:sslsocket, {:gen_tcp, #Port<0.7>, :tls_connection, :undefined},
[#PID<0.244.0>, #PID<0.243.0>]}}
It’s a common gotcha when transliterating code from Erlang to Elixir.
