The easiest way to reproduce this issue is to run the automated test in Pulp 2 Tests: <code>python -m unittest pulp_2_tests.tests.docker.api_v2.test_copy.CopyV2ContentTestCase</code>. The error occurs when this line of code is executing, inside <code>test_02_copy_manifest_lists</code>:

<pre><code class="python">client.post(urljoin(repo['_href'], 'actions/associate/'), {
'criteria': {'filters': {}, 'type_ids': ['docker_manifest_list']},
'source_repo_id': self.repo['id'],
})
</code></pre>

It also occurs when this line of code is executing, inside <code>test_02_copy_tags</code>:

<pre><code class="python">client.post(urljoin(repo['_href'], 'actions/associate/'), {
'source_repo_id': self.repo['id'],
'criteria': {'filters': {}, 'type_ids': ['docker_tag']},
})
</pre></code>
