javascript - Vue JS returns [__ob__: Observer] data instead of my array of objects

Question

I've created a page where I want to get all my data from the database with an API call, but I'm kinda new to VueJS and Javascript aswell and I don't know where I'm getting it wrong. I did test it with Postman and I get the correct JSON back.

This is what I get:

[__ob__: Observer]
length: 0
__ob__: Observer {value: Array(0), dep: Dep, vmCount: 0}
__proto__: Array

This is what I want:

(140) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, …]
[0 … 99]
[100 … 139]
length: 140
__ob__: Observer {value: Array(140), dep: Dep, vmCount: 0}
__proto__: Array

Thats my Vue template file:

<template>
    <div>
        <h2>Pigeons in the racing loft</h2>
        <div class="card-content m-b-20" v-for="pigeon in pigeons" v-bind:key="pigeon.id">
            <h3>{{ pigeon.id }}</h3>
        </div>
    </div>
</template>

<script>
export default {
    data(){
        return{
            pigeons: [],
            pigeon: {
                id: '',
                sex: '',
                color_id: '',
                pattern_id: '',
                user_id: '',
                loft_id: '',
                country: '',
                experience: '',
                form: '',
                fatique: ''
            },
            pigeon_id: ''
        }
    },
    created(){
        this.fetchPigeons();
        console.log(this.pigeons); // Here I got the observer data instead my array
    },

    methods: {
        fetchPigeons(){
            fetch('api/racingloft')
            .then(res => res.json())
            .then(res => {
                console.log(res.data); // Here I get what I need
                this.pigeons = res.data;
            })
        }
    }
}
</script>

I've tried to do it with axios aswell, but it gave me exactly the same thing. When I console it from the method it gives my data, but outside it just gives nothing.

Can also try this:

var parsedobj = JSON.parse(JSON.stringify(obj))
console.log(parsedobj)

It was brought by Evan You himself here and more info on that here

But waiting for the answer is a first step.
