Having problems using .addRowColumnDefinition() method

I am trying to create a table panel and trying to add some column definition without using the $ = go.GraphObject.Make, but I am getting this error…

and my panel looks like…


my version of gojs is the 6.14.15

You need to write

.addRowColumnDefinition(new go.RowColumnDefinition( { ... } ))

This was added in 2.3.3. There is no version 6.14.15. The latest version is 2.3.4.

upps sorry, maybe I got the versionb number in the wrong way from my project I will check both things,

but I am still getting the error…

The problem is my gojs version :'c
