Lodash objects difference

difference-object.js

_.fromPairs(_.differenceBy(_.entries(original), _.entries(target), ([key, val]) => val))

Functional programming (FP) exmaple: 🥇

import { transform, isEqual, isObject } from "lodash/fp";

const _transform = transform.convert({
	cap: false
});

export function differenceObject(targetObj, baseObj) {
	const iteratee = (result, value, key) => {
		if (!isEqual(value, baseObj[key])) {
			const valIsObj = isObject(value) && isObject(baseObj[key]);
			result[key] = valIsObj ? differenceObject(value, baseObj[key]) : value;
		}
	};
	return _transform(iteratee, null, targetObj);
}

Hi, I am getting the error: [ts] Property 'convert' does not exist on type 'Transform'.

my code:

import { transform, isEqual, isObject} from "lodash/fp";
const _transform = transform.convert({
	cap: false
});

Is this a typescript version issue?

"@types/lodash": "^4.14.106",
 "lodash": "^4.17.5",
 "tslint": "5.8.0",
 "typescript": "2.7.2"

Thanks.
