Column Expression Node for Trimming

Hi all,
I’m trying to use column expression to trim multiple columns at the same time, but I randomly get this error on some String type columns
Not familiar with Java, anyone knows why this happens?

Execute failed: java.lang.NoSuchMethodException: Can’t unambiguously select between fixed arity signatures [(java.lang.String), (java.lang.String)] of the method org.knime.expressions.base.sets.string.StringExpressionJavaMethodProvider.strip for argument types [null]

Hi there!

In this case randomly means once you get error for column and next time for the same column with same values you do not get error or only for some columns you get error and for others you do not?

In any case not sure what is happening so if you could share a workflow example where this occurs I can take a look.

Br,
Ivan
