@Shivarp1 - You're not allowed to pass `RUN` statements into the operator.
You need to start with a pre-built image.
Try this task definition:
```
task = KubernetesPodOperator(
dag=dag,
task_id="xcom_test",
name="test_xcom_failure",
namespace="default",
in_cluster=False,
config_file="/path/to/kube/config",
is_delete_operator_pod=True,
image_pull_policy="IfNotPresent",
image="alpine:3.12",
do_xcom_push=True,
retries=0,
cmds=["/bin/sh", "-c"],
arguments=["mkdir -p /airflow/xcom; echo '{\"success\": false}' | tee
/airflow/xcom/return.json; exit 1"],
)
```
