Problem with object expression containing getters and setters

When running:

var esformatter = require('esformatter');

// for a list of available options check "lib/preset/default.json"
var options = {
    // inherit from the default preset
    preset : 'default',
    indent : {
        value : '  '
    }
};

var fs = require('fs');
var codeStr = fs.readFileSync('file.js').toString();

// return a string with the formatted code
var formattedCode = esformatter.format(codeStr, options);
console.log(formattedCode)

And file.js contains:

var o = {
    a: 0,
    get b() {}, 
    set c(x) {}
};

I get no error, but with:

var o = {
    get b() {}, 
    set c(x) {}
};

I get:
