title: Custom actions cannot be specified in projects which are not created using custom category
body: <p>I'm trying to migrate an old Dialogflow action to Actions Builder, using the migration tool in the Actions Console.</p>
  <p>When I press &quot;Migrate&quot; button, the console error message pops up with a text:</p>
  <p>&quot;<em>Custom actions cannot be specified in projects which are not created using custom category.</em>&quot;</p>

  <p>My project is &quot;News &amp; magazines&quot; category.</p>
  <p>Searching for solution I've found only Reddit <a href="https://www.reddit.com/r/GoogleAssistantDev/comments/m5d6lp/custom_actions_cannot_be_specified_in_projects/" rel="nofollow noreferrer">post</a>.
  Unfortunately, no solution offered.</p>
  <p>Has anyone run into this?</p>
