Locust does response with 2xx but fails to gather request statistics - http

Question

I am trying to do a local load testing with Locust. I got the test environment up and running and a local build is also working. I am trying to test the responses of a local path and the response I get in the terminal is correct. But the Locust UI and also the statistics after terminating the test give me 100% fail results.
For creating the locust code (I am pretty new to it) I use the postman content and adjusted it. This is the Code for Locust:
from locust import HttpLocust, TaskSet, task, between
import requests
url = "http://localhost:8080/registry/downloadCounter"
payload = "[\n {\n \"appName\": \"test-app\",\n \"appVersion\": \"1.6.0\"\n }\n]"
class MyTaskSet(TaskSet):
#task(2)
def index(self):
self.client.get("")
headers = {
'Content-Type': 'application/json',
'Accept':'application/json'
}
response = requests.request("POST", url, headers=headers, data = payload)
print(response.text.encode('utf8'))
class MyLocust(HttpLocust):
task_set = MyTaskSet
wait_time = between(2.0, 4.0)
For the Locust swarm I used just basic numbers:
Number of total users to simulate: 1
Hatch Rate: 3
Host: http://localhost:8080/registry/downloadCounter
I do not get any results there, the table stays blank. I guess it has something to do with the json format but I am not able to find the solution myself.
I also put a Screenshot of the Terminal response after termination in this post.
Thank you in advance for your help!
Best regards

This helped:
from locust import HttpLocust, TaskSet, task, between
import requests
url = "http://localhost:8080/registry/downloadCounter"
payload = "[\n {\n \"appName\": \"test-app\",\n \"appVersion\": \"1.6.0\"\n }\n]"
headers = {'Content-type':'application/json', 'Accept':'application/json'}
class MyTaskSet(TaskSet):
#task(2)
def index(self):
response = self.client.post(url = url, data = payload, headers=headers)
print(response.text.encode('utf8'))
print(response.status_code)
class MyLocust(HttpLocust):
task_set = MyTaskSet
wait_time = between(2.0, 4.0)
