What steps did you take and what happened:

I tried to create cluster using the following command:

IBMCLOUD_API_KEY=<api-key-here> \
  IBMPOWERVS_SSHKEY_NAME="sharath-sshkey" \
  COS_BUCKET_REGION="us-south" \
  COS_BUCKET_NAME="power-oss-bucket" \
  COS_OBJECT_NAME=capibm-powervs-centos-streams8-1-28-4-1707287079.ova.gz \
  IBMACCOUNT_ID="c265c8cefda241ca9c107adcbbacaa84" \
  IBMPOWERVS_REGION="wdc" \
  IBMPOWERVS_ZONE="wdc06" \
  IBMVPC_REGION="us-east" \
  IBM_RESOURCE_GROUP="ibm-hypershift-dev" \
  BASE64_API_KEY=$(echo -n $IBMCLOUD_API_KEY | base64) \
  clusterctl generate cluster capi-powervs-sharath --kubernetes-version v1.28.4 \
  --target-namespace default \
  --control-plane-machine-count=3 \
  --worker-machine-count=1 \
  --from=./templates/cluster-template-powervs-create-infra.yaml | kubectl apply -f -

The cluster creation was failing with the following error: imageImport operation failed::download of image file capibm-powervs-centos-streams8-1-28-4-1707287079.ova.gz from power-oss-bucket has failed, error:file /images/import//104441157637224-capibm-powervs-centos-streams8-1-28-4-1707287079.ova.gz not found

What did you expect to happen: Successful cluster creation
