Publishing a Google Docs Add-on: Project Key is not associated with the current project

Question

I am attempting to publish a simple Google Docs add-on, following these instructions: Publishing an Add-on

However when completing the configuration for Google Apps Marketplace SDK, I enter my script project key (found from file --> project properties) and receive the following error: 'Project Key is not associated with the current project.'

Only instance where I can find someone with the same problem (here) occurred when they created a project on the Google Developers Console instead of going through resources --> Advanced Google Services. This is not the reason for my error, can anyone shred any light onto my problem?

Any help would be gratefully received, Connor

Answer 1

Kept trying, did not change the way I tried publishing nor the project key I was entering and it worked after so many retries. Wish I could give a more detailed answer...

Answer 2

I was able to fix by combining two successful responses from this post:

1. use version number, and only the number, e.g. "1" -- Do not use "v1.0" or "Version 1 on Oct 1, 6:10 AM" or your deployment's Description

2. After completing step 1, delete your entry in field 'Docs Add-On Project Script ID', then re-enter it -- the page seems to not re-evaluate your changes unless you do this; I had tried saving multiple times before doing this with no success using the correct version number and script ID.
