Which feature allows replacing problematic RegEx expressions during the commit and deployment process?

The feature that allows for replacing problematic RegEx expressions during the commit and deployment process is Global Find and Replace Rules. This functionality is essential for ensuring that any undesirable or incorrect patterns in code or configuration files can be efficiently addressed before deployment.

Global Find and Replace Rules provide a systematic way to identify and modify expressions that can potentially lead to issues within the environment where they are deployed. By utilizing this tool, teams can maintain the integrity of their deployments and avoid pitfalls associated with faulty regular expressions that may disrupt functionality.

In contrast, while Custom Scripts can also manipulate text and data, they often require more setup and may be less straightforward for addressing RegEx directly during the deployment process. Deployment Tasks are focused on orchestrating the steps of the deployment instead of handling regex issues explicitly. Environment Variables are used for configuration purposes and do not address regular expressions directly. Hence, Global Find and Replace Rules stand out as the most effective solution for this specific need.
