Problems with async await in the constructor of a typescrip class vuex and axios

I am programming the client of an api with typescript. I use axios and vuex,

this is the code

import { CredentialsInterface } from '../store/Interfaces/auth';
import Store from '@/store/index';
import axios from 'axios';


class AuthenticateClient {
    http: any;
    credentials: CredentialsInterface;
    constructor() {
        this.credentials = Store.getters.credentials;
        console.log(this.credentials);

        this.http = axios.create({
            baseURL: 'https://api.dashboarda.proyect',
            headers: {
                Accept: 'application/json',
                'Content-Type': 'application/json',
                Authorization:
                    this.credentials.tokenType + ' ' + this.credentials.token
            }
        });
    }

    async get(endPoint: string, data: any) {
        console.log(this.http);
        try {
            return await this.http.get(endPoint);
        } catch (error) {
            if (error.response.status == 401) {
                Store.commit('deleteSession');
            }
        }
    }

    async post(endPoint: string, data: any) {
        try {
            return await this.http.post(endPoint, data);
        } catch (error) {
            if (error.response.status == 401) {
                Store.commit('deleteSession');
            }
        }
    }
}

export default new AuthenticateClient();

The problem you have is that it does not initialize the token and the token_type

These are the headers with which the request comes out:

And in the console if the credentials are initialized

I know it's a synchronization problem because when the function is executed, the vuex variables are not yet loaded.

However I can't return a promise to the constructor or I don't know how to do this.
