Fetch from plugin API

I’m experimenting with fetch

const opt: FetchOptions = {
  method: "GET"
};
fetch('https://google.com/api/v1/users/profiles/?format=api', opt)
.then(res => res.text())         
.then(text => console.log("+++"))  
.catch(c=> console.log("--"));

nothing is requested. console shows this error:

figma_app.min.js.br:formatted:1366 Error: Syntax error on line 1: Unexpected token .
    at vXt (figma_app.min.js.br:formatted:260853:13)
    at async figma_app.min.js.br:formatted:261468:50

This snippet causes the error. because if I comment it the rest works as expected.
