无法发布 /api/sentiment

我正在邮递员中测试 /api/sentiment 的端点，但我不确定为什么会收到 cannot POST 错误。我相信我传递了正确的路由并且服务器正在侦听端口 8080。所有其他端点都运行没有问题，所以我不确定是什么导致了这里的错误。

const cors = require("cors");

app.use(cors(corsOptions));

    console.log("Successfully connect to MongoDB.");
    initial();
  })
  .catch(err => {

// set port, listen for requests
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}.`);
});

function initial() {
  Role.estimatedDocumentCount((err, count) => {
    if (!err && count === 0) {
      new Role({
