Unable to import default Business Application kjar project into Business Central

I am following the documentation provided in https://docs.jboss.org/jbpm/release/7.33.0.Final/jbpm-docs/html_single/. Section 3.7.6.3, Import your business assets project into Business Central. On following the steps to import the project I am getting the following error in Business Central There are no projects available to import. Check the URL, the credentials, and if there's a master branch in the repository. I have also read https://access.redhat.com/solutions/3455191 but am still getting the same error.
