Error code 4 and empty error message

[JimmyRice]

Description

I'm working on a simple console application, and an internal error has occurred when I'm requesting an API.

Code

string steamId;

cout << "Provide a Steam ID: ";
cin >> steamId;

cout << "Working on it...";
cout << endl << endl;

const string path = "https://public-api.tracker.gg/v2/csgo/standard/profile/steam/" + steamId;

cpr::Url url = cpr::Url{path};
cpr::Header header = cpr::Header{{"TRN-Api-Key", api_config::get_token()}};
cpr::Response response = cpr::Get(url, header);

cout << response.status_code << endl;
cout << static_cast<int>(response.error.code) << endl;
cerr << response.error.message << endl

Expected Behavior

Expect the request from the API server to be received correctly and output via response.text

Actual Behavior

response.status_code is 0 response.error.code is 4 response.error.message is empty

Context

I can't get a response from the API server

Thanks for reporting! Error code 4 stands for an internal error inside curl. Could you please provide a minimal example project with all your CMake stuff, so I can reproduce it?

Based on the following line I think something is wrong with the TLS configuration.

-- CA path only supported by OpenSSL, GnuTLS or mbed TLS. Set CURL_CA_PATH=none or enable one of those TLS backends.

And could you please paste the complete log from your CMake configure phase (cmake ..)?

Hi! Thank you so much for taking the time to respond to me!

I have good news on my side, when I created a new sample project and tested it, I found it worked, so I reopened my simple console application and found that the requests were working. So there seem to be no more problems at the moment.

Thank you so much.
