Example Code

from langchain_community.agent_toolkits.github.toolkit import GitHubToolkit
from langchain_community.utilities.github import GitHubAPIWrapper

 # Set your environment variables using os.environ
        os.environ["GITHUB_APP_ID"] = 'app id', it's a 3 digit one
        os.environ["GITHUB_APP_PRIVATE_KEY"] = 'path to pem file'
        os.environ["GITHUB_REPOSITORY"] = 'username/name of the repo'

        self.llm = 'Bedrock model'

    def load(self):
        llm = self.llm
        github = GitHubAPIWrapper()
        toolkit = GitHubToolkit.from_github_api_wrapper(github)
        tools = toolkit.get_tools()

        # STRUCTURED_CHAT includes args_schema for each tool, helps tool args parsing errors.
        agent = initialize_agent(
            tools,
            llm,
            agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,

Description

Hello! I'm getting an error while I try to integrate langchain's github utility with an internal app. I'm using an enterprise github account and while I try to execute the code, I receive the following error:

github.GithubException.GithubException: 401 {"message": "Integration must generate a public key", "documentation_url": "https://docs.github.com/rest"}

I've tested the code with a personal github account and it works. In this case, the app id generated has only 3 digit and not the 6 that documentation says.

System Info

Python version : 3.9.2

Hello @mesturrica! I'm Dosu, an AI bot that can assist you with bug fixes, answer questions about LangChain, and help you become a contributor. While we're waiting for a human maintainer to jump in, feel free to ask me anything. Let's get started!

The error message you're encountering typically indicates that the private key for your GitHub App is not correctly set up. The private key is used in the Auth.AppAuth function in your code.

To resolve this issue, you need to ensure that the private key for your GitHub App is correctly generated and provided. Here are the steps to do so:

1. Go to your GitHub App's settings page on GitHub.
2. In the "Private keys" section, click on "Generate a new private key".
3. A new private key will be generated and downloaded automatically. This is a .pem file.
4. You need to provide this private key to the Auth.AppAuth function in your code. You can do this by reading the file and passing the contents to the function.

Here is an example of how you can read the private key from the .pem file and pass it to the Auth.AppAuth function:

with open('path_to_your_pem_file.pem', 'r') as file:
    private_key = file.read()

auth = Auth.AppAuth(
            github_app_id,
            private_key,
        )

Please replace 'path_to_your_pem_file.pem' with the actual path to your .pem file.

Remember to keep your private key secure and do not expose it in your code or version control system.

You can find more information about this in the LangChain's GitHub utility.

If you continue to experience issues, please provide more details about the steps you're taking and any additional error messages you're seeing.

In the GitHub integration we need to pass a base url so that it will be able to generate the key. Otherwise it'll pass as api.github.com which would be invalid for a enterprise client

try:
      from github import Auth, GithubIntegration

except ImportError:
    raise ImportError(
        "PyGithub is not installed. "
        "Please install it with `pip install PyGithub`"
    )

try:
    # interpret the key as a file path
    # fallback to interpreting as the key itself
    with open(github_app_private_key, "r") as f:
        private_key = f.read()
except Exception:
    private_key = github_app_private_key

auth = Auth.AppAuth(
    github_app_id,
    private_key,
)

## Added codes
base_url = get_from_dict_or_env(values, "base_url", "GITHUB_BASE_URL") or "https://api.github.com"
gi = GithubIntegration(auth=auth, base_url=base_url) ## Proposed Solution
