Basic string transformations not working

Hi Team,

I observed that basic string transformations are not working, few of the scenarios have been listed below:

1. Trimming spaces from the text
2. Changing the text from uppercase to lowercase and vice-versa

I have used both the mapper and conditional snap however haven’t found any luck to it.

Examples for the above-listed scenario:
(1) Text is Darsh and if I put the transformation to change this to uppercase, it should return DARSH however the end result remains as is

(2) Text is " Darsh", after using trim(), trimLeft(), trimRight(), the expected result should be “Darsh” however the end result doesn’t change.

Any help on this would be highly appreciated.

Regards,
Darsh
