Pipeline step runs successfully but no change to code on branch

[natward42]

I am trying to use this to replace the path of some databricks notebook paths in a json files. The json files will have fields like this:
"notebookPath": "/Repos/<username>/<Repo>/notebooks/<path to notebook ...>",
I just need to change this to:

"notebookPath": "/notebooks/<path to notebook ...>",

I've used the following configuration:

`
steps:

• task: knom.regexreplace-task.regex-replace.RegexReplace@3
  displayName: 'RegEx Find & Replace: Replace Databricks Repo Paths in Pipelines'
  inputs:
  InputSearchPattern: 'pipeline/.json'
  FindRegex: '(/Repos/(.)/notebooks)/'
  ReplaceRegex: '$1(notebooks)'
  UseUTF8: false
  UseRAW: false
  `

But no change appears in the code on the branch.
