Using async requires async function, but my function is async

Question

I\'m adapting a library that uses callback to use Promises. It\'s working when I use then(), but it doesn\'t work when I use await.

Answer 1

You don't read that error message right: the problem isn't the function you're calling but the function you're in.

You may do

(async function(){
    await dbc.solve(img);
    // more code here or the await is useless
})();

Note that this trick should soon enough not be needed anymore in node's REPL: https://github.com/nodejs/node/issues/13209
