- Is this a typo?
- The MISSING operator requires a column as the argument, not a variable.
You could try the Column Expressions node with the isMissing
function, but I think you’re going to have a hard time with using a variable.
Have you tried matching the actual value of the string variable, which is going to be “missing” when it’s a string?
