[Vuejs]-Uncaught (in promise) TypeError: Cannot set property 'status'

You shouldn’t check the response status anyway beacuse if isn’t 200(OK), the code will execute the next callback that is .catch() and here you can handle the error.

I was able to get rid of the error.response.status undefined error with this:

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;
