Bug: Number to String, String to Number

Hi,
There is a bug in the String to Number and Number to String nodes.
In the column selection node, choose the Exclude button so that columns in the include list Can change dynamically.
Now, it results in an error when you do in fact change the workflow data columns such that less columns are now available in the include list compared to before. You simply run the workflow without reconfiguring the node and it errors about missing columns.
This is unexpected behaviour.

@richards99, could you check if enforce inclusion option is used. If yes, it may be a reason of the error.

No, this was not chosen. It seems odd behaviour with these 2 nodes only, other nodes are configured the same without issues.

Simon.

Hello @richards99,

you are right. This is a bug and there is already ticket to handle (Internal reference: AP-13839). Will give it +1.

See here for a workaround: Number to String enforcing not working
