Apache Beam Pipeline Returns Blank Output

[asif6544]

I am a first-time contributor to Apache Beam and noticed an issue where the pipeline runs successfully but produces blank output.

The job completes without any errors or warnings, but no output data is generated, which makes it difficult to understand whether the pipeline executed correctly.

Expected Behavior:
The pipeline should produce the expected output after successful execution.

Actual Behavior:
The pipeline finishes successfully, but the output is blank.

Environment:

• Apache Beam version: Not sure
• SDK: Python
• Runner: DirectRunner
• Operating System: Windows

Steps to Reproduce:

1. Create a simple Apache Beam pipeline
2. Run the pipeline using DirectRunner
3. Observe that the output is blank
