I'm trying to run the following probot using AWS Lambda that's getting events from a GHE instance.

1. I used the example project and update the app.js to use the bot code.
2. I also updated https://github.com/renovatebot/renovate-approve-bot/blob/80e0b5e0ea1d0b0b48862de39b813dce6cfd3d57/index.js#L47 to be return context.octokit.pulls.createReview(params); instead.

When the lambda triggers I am getting the following error

START RequestId: e62820aa-733b-4ef4-b750-c82ca20074fc Version: $LATEST

I've set the following environment variables for the lambda

APP_ID
PRIVATE_KEY = (the value is from cat ghe_app_privateKey.pem)
WEBHOOK_SECRET
NODE_ENV
LOG_LEVEL

Running all this in nodejs12.x

Figured it out, needed to update the code line to this

      const params = context.pullRequest({ event: APPROVE });
      return context.octokit.pulls.createReview(params)
