python
create_task_run(task_run: schemas.actions.TaskRunCreate, response: Response, db: PrefectDBInterface = Depends(provide_database_interface), orchestration_parameters: Dict[str, Any] = Depends(orchestration_dependencies.provide_task_orchestration_parameters)) -> schemas.core.TaskRun

Create a task run. If a task run with the same flow_run_id, task_key, and dynamic_key already exists, the existing task run will be returned.

If no state is provided, the task run will be created in a PENDING state.
