Wrong when expect toEqual

[nguyenvanvy1999]

How can we reproduce the crash?

Code:

export const aes256Encrypt = (
	data: string | Record<string, any> | Record<string, any>[],
	key: string,
	iv: string,
): string => {
	const cipher: Cipher = crypto.createCipheriv(env.JWT_ENCRYPT_METHOD, key, iv);
	return Buffer.from(
		cipher.update(JSON.stringify(data), "utf8", "hex") + cipher.final("hex"),
	).toString("base64");
};

export const aes256Decrypt = <
	T extends string | Record<string, any> | Record<string, any>[],
>(
	encrypted: string,
	key: string,
	iv: string,
): T => {
	const buff: Buffer = Buffer.from(encrypted, "base64");
	const decipher: Decipher = crypto.createDecipheriv(
		env.JWT_ENCRYPT_METHOD,
		key,
		iv,
	);
	return JSON.parse(
		decipher.update(buff.toString("utf8"), "hex", "utf8") +
			decipher.final("utf8"),
	);
};

And test case what is wrong:

		it("Should encrypt and decrypt object data", (): void => {
			const data: Record<string, any> = { for: "bar", bar: 1 };
			const encrypted: string = aes256Encrypt(data, key, iv);
			expect(typeof encrypted).toBe("string");
			const decrypt: Record<string, any> = aes256Decrypt<Record<string, any>>(
				encrypted,
				key,
				iv,
			);
			console.log(decrypt);
			console.log(data);
			expect(typeof decrypt).toBe("object");
			expect(decrypt).toEqual(data);
		});

I think the issue on end expect: expect(decrypt).toEqual(data);

Relevant log output

Hello @Jarred-Sumner .So sorry but after that crash, I can not reproduction any time. I was not change any code, but it work now. So weird. Btw, thanks about your feedback

[nguyenvanvy1999]

Of course, you can see my test case on this repository: https://github.com/nguyenvanvy1999/elysia/blob/main/test/util/token.test.ts
Test case was crash from line 57 - 68
