Axios sends a lot of strange code in the response, why is that?

Question

Vue.js

There is a local educational application. Back: laravel api, front: VueJS
Authentication implemented (only an authenticated user can send a request)
When getting a request from the front, the database receives status 200, but in response I get something strange (like a lot of span tags), instead of a record from the database. I send headers.
Here is the request:

const token = this.state.auth.token
            await axios.get('http://laravel.api/api/tasks', {headers: {
                'Content-Type': 'application/json',
                'Authorization': `Bearer ${token}`
            }})

Here's what comes in Response :

<script> Sfdump = window.Sfdump || (function (doc) { var refStyle = doc.createElement('style'), rxEsc = /([.*+?^${}()|\[\]\/\\])/g, idRx = /\bsf-dump-\d+-ref[012]\w+\b/, keyHint = 0 <= navigator.platform.toUpperCase().indexOf('MAC') ? 'Cmd' : 'Ctrl', addEventListener = function (e, n, cb) { e.addEventListener(n, cb, false); }; refStyle.innerHTML = 'pre.sf-dump .sf-dump-compact, .sf-dump-str-collapse .sf-dump-str-collapse, .sf-dump-str-expand .sf-dump-str-expand { display: none; }'; (doc.documentElement.firstElementChild || doc.documentElement.children[0]).appendChild(refStyle); refStyle = doc.createElement('style'); (doc.documentElement.firstElementChild || doc.documentElement.children[0]).appendChild(refStyle); if (!doc.addEventListener) { addEventListener = function (element, eventName, callback) { element.attachEvent('on' + eventName, function (e) { e.preventDefault = function () {e.returnValue = false;}; e.target = e.srcElement; callback(e); }); }; } function toggle(a, recursive) { var s = a.nextSibling || {}, oldClass = s.className, arrow, newClass; if (/\bsf-dump-compact\b/.test(oldClass)) { arrow = '&#9660;'; newClass = 'sf-dump-expanded'; } else if (/\bsf-dump-expanded\b/.test(oldClass)) { arrow = '&#9654;'; newClass = 'sf-dump-compact'; } else { return false; } if (doc.createEvent && dump-ellipsis-note{color:#1299DA}</style><pre class=sf-dump id=sf-dump-487296104 data-indent-pad="  "><span class=sf-dump-note>Illuminate\Database\Eloquent\Collection</span> {<a class=sf-dump-ref>#1221</a><samp data-depth=1 class=sf-dump-expanded>
  #<span class=sf-dump-protected title="Protected property">items</span>: <span class=sf-dump-note>array:3</span>

this is not the whole response. there are still a lot of similar lines ..
What could be the problem?
