I created a yaml file for my project’s configuration file and I get this error when trying to pull the regex from this yaml file.

Error:
exception in thread "main" while scanning a double-quoted scalar

config.yml

regex: "\((.*?)\)"

I edited my configuration file as follows and the error is resolved

config.yml

regex: "((.*?))"

But this time I break the regex and my filtering is not successful

Matcher matcher = Pattern.compile(config.getRegex()).matcher(message);
