removing backslashes in mule 4 dataweave transformation

Question

I am fetching data from SQL Server Database and transforming it into JSON in Mule 4. My input has a single backslash and converted to double backslashes. I only need a single backslash in my output.

Input example:

abchd\kdgf

Output is:

"abchd\\kdgf"

It should be:

"abchd\kdgf"

Anyone can help with this data weave transformation?

Answer 1

In JSON strings the backslash character is the escape character, and has to be escaped itself to represent a single backlash. That's how JSON works, it is not a Mule issue.

Answer 2

Here single slash treated internally as double slash. Try the dataweave expression like below

payload replace /([\\])/ with ("")

Hope it helps
