If the regex match the string used as replacement, the method will fail to replace the line

2024-03-18T23:58:06+00:00    error: Comment is 'Search and replace string'
2024-03-18T23:58:06+00:00    error: Errors encountered when actuating replace_patterns promise 'DNS1(.*)'

The documentation of the method does not mention this behavior, and it is not clear why the method is not working.
