Error when registering a dynamic module

[Paul S]

This is Node.js - I get an error 401 - "The request is not from a Connect app." when doing a POST request as follows:

const someMacro = {
  dynamicContentMacros: [
    {
      key: 'somemacro',
      name: {
        value: 'Some Macro'
      },
      documentation: {
        url: 'https://docs/...'
      },
      url: '/macro/some/some-macro.html',
      bodyType: 'rich-text',
      icon: {
        width: 72,
        height: 72,
        url: '/icons/somemacro/somemacro.png'
      },
      cacheable: true,
      description: {
        value: 'Some Macro'
      }
    }
  ]
};

export async function doSomething(register: any): Promise<any> {
  if (!register) {
    return null;
  }
  return window.AP.request({
    url: `/rest/atlassian-connect/1/app/module/dynamic`,
    type: 'POST',
    contentType: 'application/json',
    data: JSON.stringify(someMacro)
  }).catch(err => {
    return err;
  });
}

Which is as per https://developer.atlassian.com/cloud/confluence/rest/api-group-dynamic-modules/#api-atlassian-connect-1-app-module-dynamic-post

so what's wrong?!

@Paul SRegistering dynamic modules is only allowed for connect applications.  If your app is not installed in Confluence Cloud, you can't use that API.

Since the app IS installed in a cloud instance, what else could it be?
