Getting error Failed to create workflow missing TTL

[rajsuvariya]

Hi team, I am pretty new to cadence and was trying to implement hello world but getting below error

2023-10-05T10:30:50.695+0530    INFO    internal/internal_worker.go:834 Started Workflow Worker {"Domain": "test-domain", "TaskList": "cadence-samples-worker", "WorkerID": "74592@BLRETV-C02GL33D.local@cadence-samples-worker@256dcb1f-1769-4183-9604-174160f79e7a"}

Below is my code in Go

func startWorkflow() {
	// This workflow ID can be user business logic identifier as well.
	workflowID := "cron_" + uuid.New().String()
	startTime := int32(60)
	domainName := "test-domain"

	logger, workflowClient := BuildLogger(), BuildCadenceClient()

	startRequest := shared.StartWorkflowExecutionRequest{
		WorkflowId: &workflowID,
		Domain:     &domainName,
		TaskList: &shared.TaskList{
			Name: &domainName,
		},
		ExecutionStartToCloseTimeoutSeconds: &startTime,
		TaskStartToCloseTimeoutSeconds:      &startTime,
		//DecisionTaskStartToCloseTimeout: time.Minute,

	}

	we, err := workflowClient.StartWorkflowExecution(context.Background(), &startRequest)
	if err != nil {
		logger.Error("Failed to create workflow", zap.Error(err))
		panic("Failed to create workflow.")
	} else {
		logger.Info("Started Workflow", zap.String("WorkflowID", *we.RunId), zap.String("RunID", *we.RunId))
	}
}

Can someone help with this?
