How to disable HTTP/2 for GET queries

[Zabrane]

Hi @puzza007

I'm trying to send a GET request without HTTP2.
Even if I specify {pipelining, nothing}, this query seems to be sent using HTTP2.

{ok, _} = application:ensure_all_started(katipo).
Pool = api_server.
{ok, _} = katipo_pool:start(Pool, 2, [{pipelining, nothing}]).
ReqHeaders = [{<<"User-Agent">>, <<"katipo">>}].
Req = #{url => <<"https://www.vancleefarpels.com/">>,
        method => get,
        headers => ReqHeaders,
        connecttimeout_ms => 5000,
        ssl_verifyhost => false,
        ssl_verifypeer => false}.
{ok, #{status := 200,
       headers := RespHeaders,
       cookiejar := CookieJar,
       body := RespBody}} = katipo:req(Pool, Req).
       
 ** exception error: no match of right hand side value 
   {error,#{code => unknown_error,
                 message => <<"HTTP/2 stream 1 was not closed cleanly: INTERNAL_ERROR (err 2)">>}}

Is there a way to tell katipo to not use HTTP/2?
Many thanks

Hey @Zabrane, Yes, check out the request options https://github.com/puzza007/katipo#request-options. There's an option called http_version.

@puzza007 oh, missed that one:

Req = #{url => <<"https://www.vancleefarpels.com/">>,
        method => get,
        http_version => curl_http_version_1_1,
        headers => ReqHeaders,
        connecttimeout_ms => 5000,
        ssl_verifyhost => false,
        ssl_verifypeer => false}.

Thanks a lot.
