There is little info on the screenshot
Are you sure you can use the scoring task after clustering?
I might be wrong but I can't recall using any scoring after unsupervised learning node.
Is the learning path suggesting to use scoring as it is shown on the screen shot?
In Model Studio, the Cluster node does not generate score code, therefore you cannot use the Score Data node later in your flow. The results of the Cluster node can be used as inputs to a modeling node, but the node is not treated like a modeling node.
I'm sorry that I am only able to answer why this happens, but not how to resolve it.
ETA: While the clustering results will almost surely be different, you can create your clusters in SAS Visual Analytics (use the Explore and Visualize link in the App Switcher menu that is located in the upper left corner). Once you have created a Cluster model in SAS Visual Analytics, you can right-click the canvas and select "Export model" to view and save the clustering score code.
