Error "Interaction did not trigger the preview of an action" but sendInteraction() is called

[ujja]

As I see there are some bugs in readme

1, reviewSettings -> previewSettings

async function writePreviewFromDraft(projectId = 'your-project-id') {
  // Create request payload
  const request = {
    parent: `projects/${projectId}`,
    reviewSettings: {sandbox: {value: true}},

see:

                interface IWritePreviewRequest {

                    /** WritePreviewRequest parent */
                    parent?: (string|null);

                    /** WritePreviewRequest previewSettings */
                    previewSettings?: (google.actions.sdk.v2.WritePreviewRequest.IPreviewSettings|null);

2, parent -> project (just in sendIteraction, in writePreview is it parent)

async function sendInteraction(projectId = 'your-project-id', queryText = 'example query text') {
  const request = {
    parent: `projects/${projectId}`,
    input: {query: queryText}
  };

see:

                interface ISendInteractionRequest {

                    /** SendInteractionRequest project */
                    project?: (string|null);

3 So i use this payload for sendInteraction

  const request = {
    // parent: `projects/${projectId}`,
    project: `projects/${projectId}`,
    input: {
      type: 'VOICE',
      query: 'Parler avec audiobooks'
    },
    deviceProperties: {
      surface: 'SMART_DISPLAY',
      location: {
        coordinates: {
          latitude: -90.0,
          longitude: -90.0
        },
        formattedAddress: '1600 Amphitheatre Pkwy, Mountain View, CA 94043',
        zipCode: '94043',
        city: 'Mountain View'
      },
      locale: 'en',
      timeZone: 'America/New_York'
    }

  }

but got

{"code":3,"details":"Interaction did not trigger the preview of an action.","metadata":{"internalRepr":{},"options":{}}}

And I call the writePreviewFromDraft before. What can be the problem?
