Troubleshooting
After a full day’s work, realized that the source of the problem is that I had backed up one of the source code files before editing it.
Unfortunately, the backup file was placed in a folder underneath the project’s working directory.
Remediation
To correct please do one of the following :-
- Move the folders and files outside of the project’s working directory
- Explicitly exclude the folder or file from the project
