Cannot retrieve installationAccessToken

[Milredel]

I want my back-end to get all PR of all repo of my organisation. I created a github app, installed it and got my installation id and my private key (pem certificate).
But when I run this code :

const { App } = require("@octokit/app");
const { request } = require("@octokit/request");
const APP_ID = XXXX;
const PRIVATE_KEY = "-----BEGIN RSA PRIVATE KEY-----\nXXXXXXXXX";            
const installation_id = YYYY;
const app = new App({ id: APP_ID, privateKey: PRIVATE_KEY });
const installationAccessToken = await app.getInstallationAccessToken({
    installation_id
});

All I can get is this :

{ HttpError: 'Expiration time' claim ('exp') is too far in the future
    at response.text.then.message (/Users/Morgan/dev/ezdeploy/node_modules/@octokit/request/dist-node/index.js:85:23)
    at process._tickCallback (internal/process/next_tick.js:68:7)

Am I missing something ?
Thanks for the help

OK, I had time to further investigate the issue and it seems that expirationTime for the jwt is too high.
in @octokit/app/dist_node/index.js the payload is built like that :
const payload = { iat: now, exp: now + 60 * 10, iss: id };
10 minutes seems too much in the future. I just put 8 and I managed to retrieve my installationAccessToken...

Hi @Milredel, we just fixed that very problem yesterday in octokit/app.js#36, make sure you update @octokit/app to the latest version (3.0.1)
