Something's gone wrong with connect express

[el_moreno]

I followed the tutorial at https://developer.atlassian.com/cloud/jira/software/build-a-jira-app-using-a-framework/ and I am having trouble having the plug in show. 

Here is my `credentials.json` file:

{
    "hosts": {
        "https://<my_project>.atlassian.net/": {
            "product": "jira",
            "username": "<EMAIL_ADDRESS>",
            "password": "<SAME_TOKEN_USED_FOR_FORGE_APP>"
        }
    }
}

When I navigate to my JIRA instance, I do not see the "Hello World" section at top as in the tutorial:

When I click on Apps I see the Hello World app

When I click on it I see a loading page:

I can see this in the logs:

which seems to indicate that we are serving the page but I only see the error above.

If I navigate to my ngrok URL as in 

`https://<my_ngrok>/atlassian-connect.json`

I can see the contents of the `atlassian-connect.json` file

Am I using the wrong token? Any help would be greatly appreaciate!

UPDATE:

After some more debugging, I can see the following error message in developer tools:

Before you can serve HTML content, you must sign up for an ngrok account and install your authtoken. (ERR_NGROK_6022)

I have checked to make sure the token is valid. If I start a connection using ngrok as in ngrok http 3000, I can see the connection in ngrok, but when I run npm start on the sample project I do not see a tunnel in ngrok

I found the answer. The documentation fails to mention that you need to specify the token in the ngrok node module:
