How come I run into an issue with the buildah task on the OpenShift pipeline?

[SarahMPinheiro]

Hello! I am currently working on this project and my pipeline was running successfully until I added the buildah task. Once I added the buildah task and reran the pipeline I started having issues with my git-clone task. This is the error I had received on OpenShift pipeline;

• '[' false = true ']'
• '[' false = true ']'
• '[' false = true ']'
• CHECKOUT_DIR=/workspace/output/
• '[' true = true ']'
• cleandir
• '[' -d /workspace/output/ ']'
• rm -rf /workspace/output//service /workspace/output//tests

How do I resolve this problem?
