esp_websocket_client is not able to use the global CA store (IDFGH-7589)

[0xFEEDC0DE64]

I experience problems with using the websocket client with the global CA store.
The global CA store has been enabled in sdkconfig.

I generate my websocket client config like this:

    esp_websocket_client_config_t ws_cfg = {
        .uri = url.data(),
        .task_stack = 4*1024,
        .subprotocol = "ocpp1.6",
        .pingpong_timeout_sec = 20,
        .use_global_ca_store = use_global_ca_store,
        .skip_cert_common_name_check = skip_cert_common_name_check
    };

    if (!cert.empty())
    {
        ws_cfg.cert_pem = cert.data();
        ws_cfg.cert_len = cert.size();
    }

And I get to see error messages like this:

W (13330) WEBSOCKET_CLIENT esp_websocket_client.c:416 esp_websocket_client_init(): `reconnect_timeout_ms` is not set, or it is less than or equal to zero, using default time out 10000 (milliseconds)

I'm suspecting the global_cacert is NULL message, I'm missing the crt_bundle_attach function pointer as seen in the http client and mqtt client.

Should I try to replicate the crt_bundle_attach functionality in the websocket client (and pull-request)?

How can I call esp_mbedtls_set_global_ca_store() with the right arguments to make the global CA store work with the websocket client?

I did a quick rebase of my branch and found out that you also added the option that I needed. Nice, this issue can be closed
