Enterprise onboarding Journey manual allocation NOT working

Summary:

Enterprise onboarding journey manual allocation NOT working. I provide all the details in the content area.

Content (required):

The current setup of the enterprise onboarding journey: it has 2 steps, and they have:

1) No action associated but the allocation criteria is "Checklist manually allocated or record created or approved"

2) No eligibility profiles attached

3)Not using Days for initiation or Delay duration

Expectation: I want to allocate this journey to an Employee manually, and this employee should be able to see it.

I navigate to my client group -> Allocate Checklist -> Search for the employee -> Add Checklist

And I got this error message.
