I am working on Knime for several weeks now and everything went well till now. I tryed to find a solution on internet before writing this, but I could not find anything, I hope that I am not duplicating post.
I am trying to assign colors to each unique strings in a column. For example, if i give as input :
I want to be able to have :
So I connected this node to my workflow but it is like the manager color node is not able to find any column to apply its task, as when I want to configure the node, an error window tell me that :

In have strings columns in my table, may be it is because there is too many unique of them, but I am not sure about that.
Could you please help me to figure what is happening with this node ?
