Import Project not working in Business Central

I am following the documentation as mentioned in - https://docs.jboss.org/jbpm/release/7.33.0.Final/jbpm-docs/html_single/

Section - 3.7.6. Business Application with JMS,
Sub Section - Import your business assets project into Business Central
Following the below steps:

• Go into business assets project - business-application-kjar
• Execute git init
• Execute git add -A
• Execute git commit -m "my business assets project"
• Log in to Business Central and go to projects
• Select import project and enter the following URL file:/// {path to your business application}

  /business-application-kjar

• Click import and confirm project to be imported

When I import the project I am getting the error as shown in the screenshot.
