Yes, I can reproduce in apisix 3.9.0 .
If you use curl --http1.1 will works .
Fix it need time .

[hanqingwu]

By check nginx source code, I think it still not fix .
https://github.com/openresty/lua-nginx-module/blob/master/src/ngx_http_lua_headers.c#L142

#if (NGX_HTTP_V2)
    if (mr->stream) {
        return luaL_error(L, "http2 requests not supported yet");
    }
#endif

Some one try use httpc:request_uri instead of ngx.location.capture
