Integration must generate a public key

[jqtruong]

Hello, i'm getting an error:

POST https://api.github.com/installations/4/access_tokens: 401 - Integration must generate a public key // See: https://developer.github.com/v3:

i am following this guide, and the error stems from this function call:

installation_token = @client.create_app_installation_access_token(installation_id)[:token]

in the authenticate_installation.

Do you know why that might be happening?

@jqtruong can you show me how you're creating the @client ?

[jqtruong]

@client ||= Octokit::Client.new(bearer_token: jwt)

i think i'm missing something, the :integrations, right? i am currently looking into how i can add that media type

[tarebyte]

The media type is built into the helper methods, how are you creating the jwt ?

[jqtruong]

    payload = {
        # The time that this JWT was issued, _i.e._ now.
        iat: Time.now.to_i,

        # How long is the JWT good for (in seconds)?
        # Let's say it can be used for 10 minutes before it needs to be refreshed.
        # TODO we don't actually cache this token, we regenerate a new one every time!
        exp: Time.now.to_i + (10 * 60),

        # Your GitHub App's identifier number, so GitHub knows who issued the JWT, and know what permissions
        # this token has.
        iss: APP_IDENTIFIER
    }

    # Cryptographically sign the JWT
    jwt = JWT.encode(payload, PRIVATE_KEY, 'RS256')

where PRIVATE_KEY is set by

    PRIVATE_KEY = OpenSSL::PKey::RSA.new(ENV['GITHUB_PRIVATE_KEY'].gsub('\n', "\n")) # convert newlines

[tarebyte]

@jqtruong out of curiosity, why are you converting the newlines?

[jqtruong]

:) i'm just following orders... i mean instructions steps from the guide in this section.

[jqtruong]

oh i guess it is useless in this code since it's already been converted in the environment variable.

[jqtruong]

actually, nvm, that is needed because of the step in the guide. step replaces \n with the literal characters, and the code reverses that change, for a reason i do not quite understand at the moment. either way, the original issue still happens.

do you have any new thoughts that might help me? i'm willing to try anything at this point...

[jqtruong]

closing, user error. i needed to specify the api_endpoint to my company's GHE... (facepalm)

@jqtruong I have found this issue right now, could you explain how you add api_endpoint? 😅

@jqtruong I have found this issue right now, could you explain how you add api_endpoint? 😅

Octokit.configure do |c|
  c.api_endpoint = "https://<hostname>/api/v3/"
end
