Bug Report

Description

Error when running the following command (following Linode Installation Guide) -
linode-cli linodes create
--no-defaults
--root_pass ${ROOT_PW}
--type ${LINODE_TYPE}
--region ${REGION}
--image ${IMAGE_ID}
--label ${linode_label}
--private_ip true
--tags talos-control-plane
--group "talos-control-plane"
--metadata.user_data "$(base64 -i ./controlplane.yaml)"

All environment variables are set. Even converted the entire controlplane.yaml file generated using Machine Configuration Files to base64 using a python script and supplied as argument for --metadata.user_data and still getting the same error message.
