getting signer: reading key: loading URL: unrecognized scheme: awskms://

When trying to enable cosign using an AWS KMS key, the following error is generated:

{"time":"2024-08-22T12:32:47.574645-04:00","level":"ERROR","msg":"getting signer: reading key: loading URL: unrecognized scheme: awskms://"}

My helmper.yaml looks like

k8s_version: "1.27"
import:
  enabled: true
  architecture: "linux/amd64"
  cosign:
    enabled: true
    keyRef: awskms:///alias/mykey
