I am using registerScalableTarget to set my Global Secondary Index as autoscaling. Below is my code. Seems like the scaling policy is missing in your case. Be sure that the provisioned write capacity for each GSI is equal to or greater than the provisioned write capacity of the base table.

How to make a square with circles using tikz?
