How to solve Error rendering Missile Map visualization?

[MaciejChen]

I'm trying to use the Missile Map visualization, however, every time Custom Cluster Map Visualization in dashboard with Missile Map visualization , the label shows on error.  

How can I solve this error? Thanks!

I have the same problem.

The developer was made aware of this on the Github site for this project 4 years ago, but nothing has happened.
