What platform is your computer?

Darwin 22.5.0 arm64 arm

What steps can reproduce the bug?

Example from https://www.npmjs.com/package/parent-module :

// bar.js
import parentModule from 'parent-module';

export default function bar() {
	console.log(parentModule());
	//=> '/Users/<myyser>/<path>/foo.js'
};

// foo.js
import bar from './bar.js';

bar();

bun foo.js

What is the expected behavior?

That it doesn't break and prints the foo.js path:

/Users/<myyser>/<path>/foo.js

What do you see instead?

➜ bun foo.js 
2 | 
3 | export default function parentModule(filePath) {
4 |     const stacks = callsites();
5 | 
6 |     if (!filePath) {
7 |             return stacks[2].getFileName();
             ^
TypeError: undefined is not an object (evaluating 'stacks[2].getFileName')
