Troubleshooting Zowe Launcher
The following topics contain information that can help you troubleshoot problems when you encounter unexpected behavior using Zowe™ Launcher.
Issues and development of the Zowe Launcher is managed in GitHub. When you troubleshoot a problem, you can check whether a GitHub issue (open or closed) that covers the problem already exists. For a list of issues, see the launcher repo.
Enable Zowe Launcher Debug Mode
Use debug mode to display additional debug messages for Zowe Launcher.
