Making HTTPS requests from ESP32

I am making a post request from my ESP32 S2 Kaluga kit. I have tested the HTTP request while running a server program in my LAN. I am using esp_http_client_handle_t and esp_http_client_config_t from esp_http_client.h to do this.

Now, I have a HTTPS api setup in AWS API gateway. I get following error with https now:

E (148961) esp-tls-mbedtls: No server verification option set in esp_tls_cfg_t structure. Check esp_tls API reference
E (148961) esp-tls-mbedtls: Failed to set client configurations, returned [0x8017] (ESP_ERR_MBEDTLS_SSL_SETUP_FAILED)
E (148971) esp-tls: create_ssl_handle failed
E (148981) esp-tls: Failed to open new connection
E (148981) TRANSPORT_BASE: Failed to open a new connection
E (148991) HTTP_CLIENT: Connection failed, sock < 0

How can I solve this? Thank you
