How to fix the "Your account does not belong to the same domain as this cloud project or app" error?

Question

I'm updating an app on G Suite Marketplace SDK. It used to work by just changing the script version at the "App Configuration" Tab, and click Save.

Now it posted a warning at the top of the page saying:

Your account does not belong to the same domain as this cloud project or app

and the Save button is grey and not clickable.

Error image can be seen here:

What is the issue and where should I go to check and verify the domains?

Terms:

• GCP - Google Cloud Platform
• Apps Script project - Your Apps Script file

---

Your Google Cloud Platform (GCP) project that is associated with your Apps Script project is in a default category of "No organization." That's the problem.

If you already have an organization set up in your GCP, then skip down to the "Migrate your Cloud Platform Project" section below.

If you have not created an organization in your Cloud Platform project, then you need to do that. After creating an organization, you must migrate the Cloud Platform project for your add-on in "No organization" to your Organization.

Your organization is your "company."

Your Google Workspace account (formerly G Suite) can only have one Organization provisioned with it. You probably have Cloud Platform projects that were automatically put under the "No organization" category. If you already have an Organization in your Cloud Platform project, then you won't see an option to create another one.

Create an organization in Cloud Platform Project

Migrate your Cloud Platform Project:

• Open the Cloud Platform Project for your add-on
• Open IAM & Admin
• Click Settings
• Click the Migrate link

• Choose the organization to migrate to
• Click the button:
• Wait for confirmation that the migration happened

I migrated a Cloud Project for an add-on without any problem. You can also change ownership of a Cloud Project from one Google account to another Google account.

My assumption is, that the Cloud Project isn't affected by migrating it because it's basically running independently from whatever account or organization it's associated with.

The only way to know that for sure is if someone from Google provided an answer, but the only way to get support for Cloud Projects is to buy a support plan, and the least expensive one is $100 dollars a month per user.

Google Cloud Project support plans

Technically, Apps Script is not supported by Google, and there is no Google contact person to get answers from.

With the Google Workspace Marketplace SDK, you must associate an Apps Script project with the Cloud Platform project. If you changed ownership of the Apps Script file that the Google Workspace Marketplace SDK was associated with, then there would likely be a problem.

You'd need to make sure that whoever owned the Cloud Platform Project also owned the Apps Script file. If the Apps Script file was deleted, then that would kill the add-on.
