Steps to reproduce

CryptoJS.MD5(url).toString();

✔️ Expected Behavior

Code execution nodes, such as JS, can execute common functions, such as MD5. It is best to provide the import of custom package entry to improve the use of code nodes

❌ Actual Behavior

mistakeExecution code exception

Hey @Geek-Bob! 👋 I'm here to assist you with bug fixes, answer questions, and guide you on becoming a contributor. Let's work together to resolve any issues you're experiencing.

The issue you're encountering with the CryptoJS.MD5 function in Dify version 0.3.21 might be related to the sandboxed environment restrictions. The sandboxed environment in Dify disables network/IO operations and only allows native packages. Additionally, you must use print() or console.log() to output the result, or the result will be empty ^[1][2].

To ensure that the crypto-js library is available, you can check if it is listed as a dependency in the package.json file. The crypto-js library is already included as a dependency in Dify, so no additional configuration should be required ^[3].

If the issue persists, you might want to check the logs for any specific error messages that could provide more insight into the problem. Dify records logs for all interactions, and these logs can be found in the left navigation of the application ^[4][5].

If you need to import custom packages, you can specify them in the dependencies attribute of the CodeNodeData. This will ensure that the specified packages are available when the code is executed ^[6].

If you continue to face issues, please provide more details or check the logs for specific error messages that could help diagnose the problem further.

The following methods can be used to run normally:
var crypto = require('crypto');
var md5 = crypto.createHash('md5');
But direct use:
import CryptoJS from "crypto-js";
Importing the package and then CryptoJS.MD5(' string to be encrypted ') in the code will be abnormal

To resolve the issues with using CryptoJS in your Node.js environment, you should use the CommonJS require syntax instead of the ES module import syntax. Here’s how you can do it:

1. Install crypto-js: Ensure that crypto-js is listed as a dependency in your package.json.

2. Use require syntax: Since crypto-js is a CommonJS module, you should use require instead of import. Here’s an example:

   const CryptoJS = require('crypto-js');
   
   // Example usage
   const message = "Hello, World!";
   const hash = CryptoJS.MD5(message);
   console.log(hash.toString(CryptoJS.enc.Hex));

3. Ensure compatibility with your environment: If you are using a framework like Next.js, make sure the code is compatible with both server-side and client-side environments. You might need to conditionally import crypto-js if you encounter issues with server-side rendering (SSR).

   let CryptoJS;
   if (typeof window !== 'undefined') {
       CryptoJS = require('crypto-js');
   }
   
   // Example usage
   if (CryptoJS) {
       const message = "Hello, World!";
       const hash = CryptoJS.MD5(message);
       console.log(hash.toString(CryptoJS.enc.Hex));
   }

By following these steps, you should be able to resolve the errors related to ES module loading and import syntax when using the CryptoJS library in your environment ^[1].
