I have checked the adddon server and it is running.

I am using Node.js 4.50 as per the doco.

Any help would be appreciated.

Hi @Tim_Brown,

If my understanding is correct, you are trying to follow the steps in https://developer.atlassian.com/cloud/confluence/getting-started/ and you are getting stuck since you cannot start the server.

If this is correct, then looking at the provided logs I can see that the problem here is that ngrok is not managing to create a tunnel to make the add-on server running on your local machine available over the Internet:

Failed to establish local tunnel
err = Error: ngrok is not yet ready to start tunnels

Now, I might not be the best person to answer this question, but I can see that the syntax of the example showing how to create the credentials.json file is wrong, it is not a valid JSON and this could be causing the issue you are facing.

Indeed, the example in that page shows:

 ``` json
 {
  "hosts" : {
   "": {
    "product" : "confluence",
    "username" : "<user@example.com>",
    "password" : ""
   }
  }
 }
 ```

While, in order to be a valid JSON file it should be:

 {
  "hosts" : {
   "": {
    "product" : "confluence",
    "username" : "<user@example.com>",
    "password" : ""
   }
  }
 }

Can you kindly check if your credentials.json file looks like the latter one and not like the one above (that is indeed wrong)?

Also, in case this is not helping, please notice that this is not the best place to get support on development related questions. As you can find in https://developer.atlassian.com/resources/, in order to get support on developers related questions you can either:

Ask the Developers Community: https://community.developer.atlassian.com/
Open a request in the Developers Service Desk: https://ecosystem.atlassian.net/servicedesk/customer/portal/14

Please let us know if this helps.

Cheers,
Dario

Thanks Dario,

I had already figured that the JSON was invalid and updated as per your suggestion.

I have been debugging the problem at have tracked it down to ngrok thinking there are multiple sessions open, which when looking at the status page at localhost:4040 it shows just two. I am guessing that there has been an update to ngrok that has broken this demo.

It would be good if Atlassion had a tool that maybe did some automated build and tests of their examples ;P

Thanks,

Tim.

Ran into the same issue, basically ngrok 2 is broken right now, as the server sided API was extended in a non-backwards compatible manner.

Find a little bit more elaborate answer here:

Thanks for your feedback @Tim_Brown ,

I have reproduced the issue and I have created the below development bug report in order to have the example (and the related documentation page) fixed:

[DEVHELP-3179] Issue with the Confluence Cloud 'getting started' example: it does not start due to ngrok error and typos in doc

Please watch above bug ticket in order to be updated on its status.

Have a nice day.

Hi Dario,

I've encountered the same issue. However, your link to the issue seems to be broken. I can't open the issue you shared. Also I can't find a project with key DEVHELP.
