Segmentation fault in getting secret from vault while using libvault library in c++

Question

I am trying to connect with vault using libvault library. but, i am getting segmentation fault like below

• Trying ..*....
• TCP_NODELAY set
• Connected to vault..-...net (..*.) port 8200 (#0)
• ALPN, offering http/1.1
• successfully set certificate verify locations:
• CAfile: /etc/ssl/certs/ca-certificates.crt CApath: none

Thread 5 "batch" received signal SIGSEGV, Segmentation fault.

Code i have written is below

        Vault::Token rootToken{"*******"};

        Vault::TokenStrategy tokenStrategy{rootToken};
        Vault::HttpErrorCallback httpErrorCallback = [&](std::string err) {
        std::cout << err << std::endl;
        };
        Vault::Host host{"vault.*****.***-**.***.***.net"};
        Vault:: Port port{"8200"};
        //Vault:: ConnectTimeout timeout{10000};
        Vault::Config config =        Vault::ConfigBuilder().withDebug(true).withTlsEnabled(true).withHost(host).withPort(port).build();
       
        Vault::Client vaultClient{config, tokenStrategy, httpErrorCallback};
        
         Vault::SecretMount mount{"/****/*****/*****"};
        Vault::KeyValue kv{vaultClient,mount};
      
        Vault::Path key{"**/***/***"};
     
            std::cout<<"vault check initial<<std::endl;
            

           auto response = kv.read(key);
           
          if (response) {
              std::cout<<"vault check"<<std::endl;
            std::cout << response.value() << std::endl;
          } else {
            std::cout << "Unable to read secrets" << std::endl;
          }

exception is during reading the kv.read(key)

Below is the stacktrace ...
