Index was outside the bounds of the array when click on ‘Add Planes and PointCloud’

[viknesh2020]

I followed the steps that are given in the tutorial. Captured a map data using Spatial Capture app. Did all steps for listing the maps and also added the API key. However, while clicking on the ‘Add Planes and PointCloud’ button I get the following error.

IndexOutOfRangeException: Index was outside the bounds of the array. EditorCoroutines.PlacenoteWebAPI+<AddMeshCoroutine>d__8.MoveNext () (at Assets/Placenote/Toolkits/SpatialCapture/PlacenoteWebAPI.cs:116) EditorCoroutines.EditorCoroutines.MoveNext (EditorCoroutines.EditorCoroutines+EditorCoroutine coroutine) (at Assets/Placenote/EditorCoroutines/Scripts/EditorCoroutines.cs:337) EditorCoroutines.EditorCoroutines.OnUpdate () (at Assets/Placenote/EditorCoroutines/Scripts/EditorCoroutines.cs:320) UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at /Users/builduser/buildslave/unity/build/Editor/Mono/EditorApplication.cs:200)

Am I missing something?
