Handle same path for POST and get throws Error

[seppy87]

Describe the bug

My REST server is using get for getting Informations and POST to update. But if I am using GET and POST for /settings then it will throw a served::request_error when I try to GET Request for Settings
the REST Client says Method not allowed.

Steps to reproduce

void KSecureDesktopServer::initREST() {
   //General Settings
    served::multiplexer& mux = this->multiplexer;
    auto* sender = this;
    mux.handle("/settings").get([this](served::response& res, const served::request& req) {
       this->getSettings(res, req);  //throws an exception
        });
    mux.handle("/settings").post([this](served::response& res, const served::request& req) {
        this->postSettings(res, req); }); // works
    //Get User Info
    mux.handle("/user").get([this](served::response& res, const served::request& req) {
       // this->getUser(res, req); 
        int i = 0;
        res << "SUCCESS"; //works
        }
    );
  // mux.handle("/user").post([this](served::response& res, const served::request& req) {this->postUser(res, req); });
   // mux.handle("/user").put([this](served::response& res, const served::request& req) {this->putUser(res, req); });
    //mux.handle("/user").del([this](served::response& res, const served::request& req) {this->deleteUser(res, req); });
    //Channels
    //mux.handle("/channel").get([this](served::response& res, const served::request& req) {this->getChannel(res, req); });
    //mux.handle("/channel").post([this](served::response& res, const served::request& req) {this->postChannel(res, req); });
    //mux.handle("/channel").put([this](served::response& res, const served::request& req) {this->putChannel(res, req); });
    //mux.handle("/channel").del([this](served::response& res, const served::request& req) {this->deleteChannel(res, req); });

    this->restServer = std::make_unique<served::net::server>("127.0.0.1", "8080", mux);
   
    this->restServer->run(10,false);
}

Multiplexer is a Class member and net::server is a smart pointer.

Expected behavior

can handle both requests
