Contextual filter doesn't work with the name of the entity reference, it only works with its ID why is the contextual filter below only working the the id of the entity reference ID? I would to search by name like by "Oceanography" or "Ecology and Evolution", but i'm not sure how. If i add a relationship the contextual filter doesn't even work with the ID number. Please help. Thanks in advace.
Like Drupal 7 this configuration should work for you :

But for some reason it doesn't work, so your alternative is Views Taxonomy Term Name Depth module if you are working with Drupal 8.6 or higher version:``


Install and enable the module.
Add contextual filter Content: Has taxonomy term name with Depth

Save your changes.
