Error: Uncaught TypeError - Unable to assign a value to the 'status' property

Hello everyone, I am currently facing an issue with validating the response from my server using Axios in VueJS.

axios.post('/login', {
  email: this.email,
  password: this.password
}).then(response => {
  if (response.status == 200) {
    $root.$data.auth = true;
  } else {
    alert('Uh oh');
  }
}).catch(e => {
  if (e.response.status == 422) {
    this.error = "Did you forget your login details?";
  } else {
    this.error = "Something unexpected happened: " + e.response.status;
  }
});

After successful logins, I am receiving this error in the console:

Uncaught (in promise) TypeError: Cannot set property 'status' of undefined

This is confusing for me because according to the Axios documentation, I should be able to access the response status object and use it for conditional statements. Can anyone help clarify this?

Answer №1

It is advisable not to solely rely on checking the response status, as if it is not 200(OK), the code will proceed to execute the subsequent callback which is .catch(), allowing you to effectively handle any encountered errors.

Answer №2

I managed to fix the error.response.status undefined issue by implementing the following solution:

const errStatus = (typeof error.response.status !== 'undefined') ? error.response.status : 'unknown';
const errText = (error.response.statusText != null) ? error.response.statusText : 'unknown';
const errElse = { email: [`[Error status code: ${errStatus}].....[Error status: ${errText}]......Please submit a trouble ticket`] };
this.errors = errElse;
