Why Cannot POST when sending data via axios?

Question

Vue.js

I want to send data from the form to the server

formSubmit: function () {
  let resultData = JSON.stringify(this.formData)
  axios.post('https://Домен/api/tasks/create.php', {
    data: resultData
  })
      .then(response=>{
        console.log(response);
      })
      .catch(error=>{
        console.log(error);
      })
}

formdata looks like this:

formData: {
    name: "Alex",
    geo: "Ru",
    executor: "1",
    complexity: "1",
    deadline: "2022-03-07 12:20:22",
  },

But when you call the formSubmit (@submit="formSubmit") method, this appears on the screen.

Cannot POST / here is the name of the view component.

Sent the same data to the same url via Postman, everything is fine.

Why Cannot POST, how to fix it?

upd tried again like this, indicating the content type, but the same problem

formSubmit: function () {
      let resultData = JSON.stringify(this.formData)
      axios({
        method: 'post',
        url: 'https://домен/api/tasks/create.php',
        data: resultData,
        headers: {
          "Content-type": "application/json"
        }
      })
          .then(function(response) {
            console.log('Ответ сервера успешно получен!');
            console.log(response.data);
          })
          .catch(function(error) {
            console.log(error);
          });
    }
