Summary:
Ensure setupLog.Error(nil, <errorString>) is replaced with setupLog.Error(errors.New()) to prevent missing log lines and improve debugging.

Problem:

• Using nil as the error argument results in no log entry being written.
• This led to empty pod logs in some cases.
• A mechanism should be implemented to prevent this scenario in the future.

Acceptance Criteria:

• Identify and replace all occurrences of setupLog.Error(nil, <errorString>).
• Implement safeguards to prevent similar issues.
• Verify logs are correctly written after the fix.
