Acquia Content Hub 2.x Import always fails

I am new to Acquia Content Hub 2.x Module for Drupal 9.

I tried exporting contents from my main site and it is exported successfully however when I tried importing the content on my sub/child site, it always fails.

It has an ErrorThe entity with UUID = “f4df7d6b-e197-40fb-af6e-8e8fe5c3b19a” could not be imported because it is missing from Content Hub.” even though my export is successful.

Hoping someone could help

Thank you
