Ok

- WorkflowRunnerOperationRun — Operation level information about workflow run.
  - `methodReference` string, nullable — Reference to a component version. Components are organized into a group hierarchy which serves as a qualification mechanism to avoid collisions and also to group components semantically. Component versions follow the convention of semantic versioning. The fully qualified reference of a component version follows the following syntax: `[component_group]:[component]:[component_version]`.
  - `methodRunId` string, nullable — Method run identifier. It is a string composed of the type identifier and a UUID: `method.run:[UUID]`.
  - `nestedWorkflowRunId` string, nullable — Workflow run identifier. It is a string composed of the type identifier and a UUID: `workflow.run:[UUID]`.
  - `nestedWorkflowTypeReference` string, nullable — Reference to a component version. Components are organized into a group hierarchy which serves as a qualification mechanism to avoid collisions and also to group components semantically. Component versions follow the convention of semantic versioning. The fully qualified reference of a component version follows the following syntax: `[component_group]:[component]:[component_version]`.
  - `operationName` string
  - `operationRunId` string — Operation run identifier. It is a string composed of the type identifier and a UUID: `operation.run:[UUID]`.
  - `operationRunStateHistory` WorkflowRunnerOperationRunStateHistoryItem[]
    - `changeTimestamp` string, date-time
    - `operationRunState` 'CREATED' | 'SCHEDULED' | 'RUNNING' | 'TO_BE_REPROCESSED' | 'SUCCEEDED' | 'FAILED' | 'CANCELED' | 'PROCESSING' | 'PROCESSED' | 'UNPROCESSED' — Possible states of an operation run.
  - `operationType` 'METHOD' | 'NESTED_WORKFLOW' | 'INLINE' — Possible types of an operation run in the workflow run.
  - `parameterValues` object, nullable
  - `recycled` boolean
  - `stateHistoryStatisticalSummary` WorkflowRunnerOperationRunStateHistoryStatisticalSummary — Statistical summary information about the workflow run state history.
    - `totalDuration` integer
  - `workflowRunId` string — Workflow run identifier. It is a string composed of the type identifier and a UUID: `workflow.run:[UUID]`.
