Pulp 2 to Pulp3 upgrade fails

What is strange is that I can list the docker repos:

# docker search $(hostname)/fedora
NAME                                                                                            DESCRIPTION   STARS     OFFICIAL   AUTOMATED
test-centos_8_content-2_0-fedora_docker_containers-fedora_docker_container_repo                         0
test-development-centos_8_content-fedora_docker_containers-fedora_docker_container_repo                 0
test-fedora_docker_containers-fedora_docker_container_repo                                              0
test-library-centos_8_content-fedora_docker_containers-fedora_docker_container_repo                     0

Pulp3 now also shows the repos:

# pulp container repository list
[
  {
    "pulp_href": "/pulp/api/v3/repositories/container/container/9de7f6e5-f32b-4c26-a080-366e0bd3fa8f/",
    "pulp_created": "2021-01-22T08:12:30.889021Z",
    "versions_href": "/pulp/api/v3/repositories/container/container/9de7f6e5-f32b-4c26-a080-366e0bd3fa8f/versions/",
    "latest_version_href": "/pulp/api/v3/repositories/container/container/9de7f6e5-f32b-4c26-a080-366e0bd3fa8f/versions/0/",
    "name": "Fedora_Docker_container_repo-472668",
    "description": null,
    "remote": null
  },
..

I have tried all the ways I can think of to pull the container but none of the examples in the Foreman docs work.
