Code component

A component that enables users to integrate Python or JavaScript codes into their Agent for dynamic data processing.

Scenarios​

A Code component is essential when you need to integrate complex code logic (Python or JavaScript) into your Agent for dynamic data processing.

Prerequisites​

1. Ensure gVisor is properly installed​

We use gVisor to isolate code execution from the host system. Please follow the official installation guide to install gVisor, ensuring your operating system is compatible before proceeding.

2. Ensure Sandbox is properly installed​

RAGFlow Sandbox is a secure, pluggable code execution backend. It serves as the code executor for the Code component. Please follow the instructions here to install RAGFlow Sandbox.

NOTE

If your RAGFlow Sandbox is not working, please be sure to consult the Troubleshooting section in this document. We assure you that it addresses 99.99% of the issues!

3. (Optional) Install necessary dependencies​

If you need to import your own Python or JavaScript packages into Sandbox, please follow the commands provided in the How to import my own Python or JavaScript packages into Sandbox? section to install the additional dependencies.

4. Enable Sandbox-specific settings in RAGFlow​

Ensure all Sandbox-specific settings are enabled in ragflow/docker/.env.

5. Restart the service after making changes​

Any changes to the configuration or environment require a full service restart to take effect.

Configurations​

Input​

You can specify multiple input sources for the Code component. Click + Add variable in the Input variables section to include the desired input variables.

Code​

This field allows you to enter and edit your source code.

A Python code example​

    def main(arg1: str, arg2: str) -> dict:
        return {
            "result": arg1 + arg2,
        }

A JavaScript code example​


    const axios = require('axios');
    async function main(args) {
      try {
        const response = await axios.get('https://github.com/infiniflow/ragflow');
        console.log('Body:', response.data);
      } catch (error) {
        console.error('Error:', error.message);
      }
    }

Return values​

You define the output variable(s) of the Code component here.

Output​

The defined output variable(s) will be auto-populated here.

Troubleshooting​

HTTPConnectionPool(host='sandbox-executor-manager', port=9385): Read timed out.​

Root cause

  • You did not properly install gVisor and runsc was not recognized as a valid Docker runtime.
  • You did not pull the required base images for the runners and no runner was started.

Solution

For the gVisor issue:

  1. Install gVisor.

  2. Restart Docker.

  3. Run the following to double check:

    docker run --rm --runtime=runsc hello-world

For the base image issue, pull the required base images:

docker pull infiniflow/sandbox-base-nodejs:latest
docker pull infiniflow/sandbox-base-python:latest

HTTPConnectionPool(host='none', port=9385): Max retries exceeded.​

Root cause

sandbox-executor-manager is not mapped in /etc/hosts.

Solution

Add a new entry to /etc/hosts:

127.0.0.1 es01 infinity mysql minio redis sandbox-executor-manager

Container pool is busy​

Root cause

All runners are currently in use, executing tasks.

Solution

Please try again shortly or increase the pool size in the configuration to improve availability and reduce waiting times.

Frequently asked questions​

How to import my own Python or JavaScript packages into Sandbox?​

To import your Python packages, update sandbox_base_image/python/requirements.txt to install the required dependencies. For example, to add the openpyxl package, proceed with the following command lines:

(ragflow) ➜ ragflow/sandbox main ✓ pwd # make sure you are in the right directory
/home/infiniflow/workspace/ragflow/sandbox

(ragflow) ➜ ragflow/sandbox main ✓ echo "openpyxl" >> sandbox_base_image/python/requirements.txt # add the package to the requirements.txt file

(ragflow) ➜ ragflow/sandbox main ✗ cat sandbox_base_image/python/requirements.txt # make sure the package is added
numpy
pandas
requests
openpyxl # here it is

(ragflow) ➜ ragflow/sandbox main ✗ make # rebuild the docker image, this command will rebuild the iamge and start the service immediately. To build image only, using `make build` instead.

(ragflow) ➜ ragflow/sandbox main ✗ docker exec -it sandbox_python_0 /bin/bash # entering container to check if the package is installed


# in the container
nobody@ffd8a7dd19da:/workspace$ python # launch python shell
Python 3.11.13 (main, Aug 12 2025, 22:46:03) [GCC 12.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import openpyxl # import the package to verify installation
>>>
# That's okay!

To import your JavaScript packages, navigate to sandbox_base_image/nodejs and use npm to install the required packages. For example, to add the lodash package, run the following commands:

(ragflow) ➜ ragflow/sandbox main ✓ pwd
/home/infiniflow/workspace/ragflow/sandbox

(ragflow) ➜ ragflow/sandbox main ✓ cd sandbox_base_image/nodejs

(ragflow) ➜ ragflow/sandbox/sandbox_base_image/nodejs main ✓ npm install lodash 

(ragflow) ➜ ragflow/sandbox/sandbox_base_image/nodejs main ✓ cd ../.. # go back to sandbox root directory

(ragflow) ➜ ragflow/sandbox main ✗ make # rebuild the docker image, this command will rebuild the iamge and start the service immediately. To build image only, using `make build` instead.

(ragflow) ➜ ragflow/sandbox main ✗ docker exec -it sandbox_nodejs_0 /bin/bash # entering container to check if the package is installed

# in the container
nobody@dd4bbcabef63:/workspace$ npm list lodash # verify via npm list
/workspace
`-- lodash@4.17.21 extraneous

nobody@dd4bbcabef63:/workspace$ ls node_modules | grep lodash # or verify via listing node_modules
lodash

# That's okay!
