How to proccessing Vuex array in Vue.js - vue.js

Question

I'm a new web developer. I need help getting all of the titles from all of the objects in an array. I get an array of products from an axios request. In the next step I need to process this array in a Vue component and record a single value to data. Next I need to display this data value in a multiselect's options.
Here is the axios code:
async getOrders(ctx, data)
{
return new Promise((resolve, reject) => {
axios({
url: '/orders',
data: data,
method: 'GET'
})
.then((resp) => {
ctx.commit('setOrders', resp.data.orders)
ctx.commit('setUsers', resp.data.users)
ctx.commit('setProducts', resp.data.products)
ctx.commit('updatePagination', resp.data.pagination)
resolve(resp)
})
.catch((error) => {
console.log(error)
reject(error)
})
})
},
This is my array of products recorded in Vuex store
0: {id: 6, category_id: 2, title: "Test", brand: "Тест", serial_number: "2165412315864",…}
1: {id: 7, category_id: 3, title: "Климат", brand: "Климат", serial_number: "2165412315864",…}
2: {id: 8, category_id: 5, title: "New", brand: "New", serial_number: "2165412315864",…}
This is my code to proccessing this array
computed:{
...mapGetters('order', ['users', 'products', 'orders']),
},
methods:{
getProducts(products)
{
const arr = products.map(c => c.title)
console.log('titles: ', arr); //Debug
this.options = arr
}
},
And here is the code for the multiselect
<multiselect v-model="formData.product" :options="options" :value="values" :multiple="true" :close-on-select="false" :clear-on-select="false" :preserve-search="true" placeholder="Pick some" label="name" track-by="name" :preselect-first="true">
<template slot="selection" slot-scope="{ values, search, isOpen }"><span class="multiselect__single" v-if="values.length && !isOpen">{{ values.length }} options selected</span></template>
</multiselect>
mounted() {
this.getProducts();
},

It looks like you're not sending your args by calling just this.getProducts(). You don't need to, just write this. in front of the computed value inside the method.
methods: {
getProducts () {
const arr = this.products.map(c => c.title)
this.options = arr
}
}
