We don't do urgent here. Do a search on urgent and u will see the kind of replies you get. For your answer, do a search on "null string argument". See if one of those posts help.

Describe your job fully and accurately. If you must, post the generated OSH. Ideally, post the score.

laknar - that didn't help clarify your problem at all. What stages are you using? are you calling functions from a transform stage? Are any of your string columns nullable?

Yes String columns are nullable

and Iam Calling from a transform Stage.

That means you are doing some function call in your transform stage using a null string where the function doesn't allow null values. Look at your stage variables and derivations and see which ones manipulate strings.

You need to handle nulls before you process them in a stage variable.
