I have requirement where I need to append and prepend the attribute with "$$$". how ever, Nifi expression language is appending or prepending with "\$"
For example: if attribute named "myattr" value is "This is Test"
when I do ${myattr:prepend('$$$'):append('$$$')}
I am expecting "$$$This is Test$$$"
but the output is "\$This is Test\$"
Is there any way to append or prepend the attribute with "$$$"

use 9$ instead of 3$
${myattr:prepend('$$$$$$$$$'):append('$$$$$$$$$')}
in expression language if you use 3$ are results as 1$ so we need to use 9$ if you want 3$ sign to be added to the attribute value.
Input:- "myattr" value is "This is Test"
expression:- ${myattr:prepend('$$$$$$$$$'):append('$$$$$$$$$')}
Output:- $$$This is Test$$$

what might be the reason for the extra character '\' ?

it seems like replaceText processor is replacing '$$$$$*' in the content to '\$' while replacing the flow file content!
seems like actual issue is I have an attribute namely "myattr"
when myattr is "$$This is test$$", if I replace the flowfile content with myattr, the content in the flowfile is "\$this is test\$"
