+  *   `revisionCreateTime` (*type:* `DateTime.t`, *default:* `nil`) - Output only. The timestamp for the latest revision of the workflow's creation.
+  *   `revisionId` (*type:* `String.t`, *default:* `nil`) - Output only. The revision of the workflow. A new revision of a workflow is created as a result of updating the following properties of a workflow: - Service account - Workflow code to be executed The format is "000001-a4d", where the first six characters define the zero-padded revision ordinal number. They are followed by a hyphen and three hexadecimal random characters.
   *   `serviceAccount` (*type:* `String.t`, *default:* `nil`) - The service account associated with the latest workflow version. This service account represents the identity of the workflow and determines what permissions the workflow has. Format: projects/{project}/serviceAccounts/{account} or {account} Using `-` as a wildcard for the `{project}` or not providing one at all will infer the project from the account. The `{account}` value can be the `email` address or the `unique_id` of the service account. If not provided, workflow will use the project's default service account. Modifying this field for an existing workflow results in a new workflow revision.
   *   `sourceContents` (*type:* `String.t`, *default:* `nil`) - Workflow code to be executed. The size limit is 128KB.
   *   `state` (*type:* `String.t`, *default:* `nil`) - Output only. State of the workflow deployment.
-  *   `updateTime` (*type:* `DateTime.t`, *default:* `nil`) - Output only. The last update timestamp of the workflow.
+  *   `stateError` (*type:* `GoogleApi.Workflows.V1.Model.StateError.t`, *default:* `nil`) - Output only. Error regarding the state of the workflow. For example, this field will have error details if the execution data is unavailable due to revoked KMS key permissions.
+  *   `updateTime` (*type:* `DateTime.t`, *default:* `nil`) - Output only. The timestamp for when the workflow was last updated. This is a workflow-wide field and is not tied to a specific revision.
+  *   `userEnvVars` (*type:* `map()`, *default:* `nil`) - Optional. User-defined environment variables associated with this workflow revision. This map has a maximum length of 20. Each string can take up to 4KiB. Keys cannot be empty strings and cannot start with "GOOGLE" or "WORKFLOWS".

-  Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns `UNIMPLEMENTED`. NOTE: the `name` binding allows API services to override the binding to use different resource name schemes, such as `users/*/operations`. To override the binding, API services can add a binding such as `"/v1/{name=users/*}/operations"` to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.
