Current Behavior

While doing a local source build, the CLI throws the following error and the build fails.

Expected Behavior

The build should successfully complete.

Steps To Reproduce

1. Install Shipwright in Kind or Minikube cluster
2. Install delivered cluster build strategies
3. Install Shipwright CLI
4. Create a Build with local source

shp build create sample-buildah \
--namespace="$BUILD_NAMESPACE" \
--request-timeout="10m" \
--strategy-kind="ClusterBuildStrategy" \
--strategy-name="buildah" \
--dockerfile="Dockerfile" \
--output-image="$OUTPUT_IMAGE" \
--retention-failed-limit=5 \
--retention-succeeded-limit=10
Created build "sample-buildah"

5. Run build using shipwright CLI

shp build upload \                                                     
"$BUILD_NAME" \
"$SOURCE_DIR" --follow \
--namespace="$BUILD_NAMESPACE" \
--output-image="$OUTPUT_IMAGE"
