locust: Locust doesn't exit when a load shape returns None

Hi

When locust test is run it should automatically stop running when a LoadTestShape class tick method signals a test is complete by returning None.

But the test is finished but locust is doesn’t exit, master pod restart again. I’m using Docker to run Locust. (Version: 2.1.0)

class User(HttpUser):

    def on_start(self):
        print("test is starting")

    wait_time = between(0, 0)
    tasks = {SequenceOfTasks}

    @events.test_stop.add_listener
    def on_stop(self):
        print("------------------------------------------------------------------------------------")
        print("------------------------------------------------------------------------------------")
        print("test is stopping")
        print("------------------------------------------------------------------------------------")
        print("------------------------------------------------------------------------------------")
        self.environment.runner.quit()
        self.driver.quit()


class MyCustomShape(LoadTestShape):
    stages = [
        {"duration": 60, "users": 10, "spawn_rate": 10}
    ]

    def tick(self):
        run_time = self.get_run_time()

        for stage in self.stages:
            print(run_time)
            print(stage["duration"])
            print(stage["users"])
            if run_time < stage["duration"]:
                tick_data = (stage["users"], stage["spawn_rate"])
                return tick_data

        return None

This is my worker log workerlog.txt

and it is my master log two part before restart and after restart masterlog.txt
