KB45733: "TypeError: Unable to get value of the property "ty": object is null or undefined" error displays within a Google Map widget when running a document in MicroStrategy Web

Description

In Strategy Web, users may encounter unexpected behavior when running a document containing a Google Map widget.  This particular error occurs in Presentation view mode:

TypeError: Unable to get value of the property 'ty': object is null or undefined

Steps to reproduce

Required: Google Maps has already been deployed by following KB36062: How to deploy and configure the Google Maps connector plugin in MicroStrategy Web 9.x

• Go to Strategy Web.
• Go to the project "Strategy Tutorial".
• Create a new blank report.
• Insert the Store attribute into the row, with no metrics.
   
  

• Edit the display Attribute Forms for the Store attribute to show Longitude and Latitude forms.
• Save the report and create a document from the report.
• Within the document, insert a Map widget.
• Insert Store into the widget row section and do not include any metrics
• Right mouse-click in the widget and choose 'Widget Properties.' In the widget properties, leave the properties  as default like shown below.
   
  

• Run the document in presentation view mode. The error should show up and no points should show on the map.

Why is this happening?

This is a known issue in Strategy. The impact is limited to documents in Strategy Web using the Google Map widget, when the widget contains no metrics.
 

Solution

Solution 1

Insert at least one metric within the column section of the Map widget grid in Design or Editable view mode.
 

Solution 2

Uncheck the "Apply color formatting to map" option within the widget properties.  This setting is shown below.

 
Either of the above workarounds will display the Google Map widget without error.
