delete() seems not to work in particular cases

[topheroes]

Hello,

Node 17.0.1, code:

const { refactor } = require('shift-refactor');


const code = '! function(a,b,c){ a = 1, b = 2, c = 3, console.log(200)}()';
const secondExpression = "Script > ExpressionStatement > UnaryExpression > CallExpression > FunctionExpression > FunctionBody > ExpressionStatement > .expression > .left > .left > .right";

const fs = require("fs");

var $script = refactor(code);


$script(secondExpression).delete();


console.log($script.print());

Shows error:

_\node_modules\shift-reducer\dist\director.js:68
return reducer.reduceBinaryExpression(node, { left: this[node.left.type](reducer, node.left), right: this[node.right.type](reducer, node.right) });
^

TypeError: Cannot read properties of null (reading 'type')_

Am I doing anything wrong? Please advise.

PS. Thank you for your great videos, hope you'll continue to make them someday.
