Hi everyone, please help me on the below issue. I am taking the MuleSoft.U Flow Design course and I have a free account. I'm not able to apply the transformations to the payload as the videos indicate. For example when trying to apply the upper transformation to a string, when I click Enter on the keyboard(as the video indicates), it only moves the carrier to the next line in that text box. It does not let me click Ok to apply the transformation. See the attached screenshot of the issue. I see there is an error message about a null, but I don't understand why it´s taking that string as a null value. PLEASE HELP ME! THANKS! :D
Hi @achaverri2
To use upper function, `upper` + space + string. You have a null value for `value0.code`. Use default value to prevent this exception.
Dataweave Script:
%dw 1.0
%output application/json
%var value0 = {
code: null
}
---
{
airportCode: upper (value0.code default '')
}
