I have a Google Cloud project that I want to delete.

However, when I press delete and enter the project id, I get the following error messages:

The project         


        

Answer 1

I know this is the late response to the question. However, the lien doesn't always mean payment due. You might have some projects linked with it. In my case, I have integrated projects from dialog flow and Firebase in google cloud.

Once unlinked, those projects from the main cloud project I was able to delete the project from Google Cloud.
