Error in array$arrayLength : object of type 'closure' is not subsettable

[TianyaImpression]

• rgee version: 1.1.3
• R version: 4.2.1
• Operating System: win10

I tried this example: https://github.com/csaybar/rgee/blob/examples//Array/array_transformations.R

I get an error when running this line of code array <- collection$map(makeVariables)$toArray()

I want to know where is the problem and how to solve it.

Thank you!
