Thanks for the detailed reply.
Indeed, there is an issue in version 6 with the containerized application. Thanks for reporting it.
We recently released v9.0 but by using the command “invenio-cli init rdm”, it’s still installing version 6. We will update this soon but in the meantime you can specify the version by using “invenio-cli init rdm -c v9.0”. Could you give it a try and let us know if it works?
