The ERROR message says:

Thanks, i saw that error, but i was never prompted for any login or username.
The backend/instance.yaml file contains the default initial_user_name ( is admin ) that's it

sorry, i am closing this thread, i re-did the install steps beginning with cookiecutter and all went fine.

( but i cannot close this thread )

In connection with this problem, I found out that this error occurs when the Project Title is shorter than three characters. According to his log, the thread creator used the project title "p6" and I also get this error during a make install when I use pipx run cookiecutter gh:collective/cookiecutter-plone-starter
create a new project whose title only has two characters.
Maybe you could post a note about this here or at cookiecutter-plone-starter


Interesting, and a good find. Could you please create an issue on GitHub - collective/cookiecutter-plone-starter: Cookiecutter Plone Starter is a framework for jumpstarting Plone 6 projects quickly. for that minimum project title length?

As this is collective, you can also create a PR on the repo without having signed the Plone Contributor Agreement.

But putting some time into sending in the contributor agreement makes contribution to plone/ packages easier and it a requrement. https://plone.org/foundation/contributors-agreement
