x-pack/platform/test/functional/apps/canvas/embeddables/lens.ts test case 'renders lens visualization using savedLens expression' loads 'Test Workpad' workpad.

workpad contents:

• references: []
• embeddable config

  {
    savedObjectId: 'my-lens-vis',
     timeRange: { from: '2014-01-01', to: '2018-01-01' }
  }
  

Running this config through lens transforms returns the following error "Error: Why are attributes undefined?" because lens thinks its a by-value embeddable because savedObjectRef is missing. Instead, canvas should convert savedObjectId: 'my-lens-vis' into the reference shape lens transform is expecting.

Marked as critical because its blocking #255555
