使用异步函数的DataMaps js问题

Question

I've created a script that gets data from API, format the data and use it using DataMaps http://datamaps.github.io/ .

In my.js file i can simply call:

var map = new Datamap({element: document.getElementById('container')});

And it will render the map in selected div. The problem is that if i use it inside async function to get the data from an API and render the map filled with API's data I get this error:

Uncaught (in promise) TypeError: Cannot read property 'select' of undefined
    at Datamap.drawSubunits (datamaps.all.js:184)
    at draw (datamaps.all.js:789)
    at Datamap.draw (datamaps.all.js:768)
    at new Datamap (datamaps.all.js:730)
...

I even get this error if i just call the map this way inside the async function, so the data is not the problem:

async function fetchData() {
    try {
        const response = await fetch('https://corona.lmao.ninja/v2/countries?yesterday=&sort=');
        const data = await (response.json());
        var map = new Datamap({element: document.getElementById('container')});
        return data;
    } catch (error) {
        console.error(error);
    }
}
fetchData();

If I put var map = new Datamap({element: document.getElementById('container')}); outside the function it works. I have no clue about it.

Any help would be appreciated. First post and english is not my main language.

judging by mistake, you use the nonexistent variable 'select' or an empty variable. maybe I was wrong in spelling my English level is not so good
