aws_kms_key: "key_usage" must be ENCRYPT_DECRYPT or not specified

[koooge]

Hello. :)
terraforming kmsk generated below setting.
But terraform plan with the .tf file shows aws_kms_key: "key_usage" must be ENCRYPT_DECRYPT or not specified error.
Is this intended?

resource "aws_kms_key" "<id>" {
    description             = ""
    key_usage               = "ENCRYPT/DECRYPT"
    is_enabled              = true
    enable_key_rotation     = false

    policy = <<POLICY
