[Python] Connection error while running locust load testing using Gunicorn for FastAPI

I am trying to do load testing using locust for FastAPI application using gunicorn

below is my load testing code

from locust import HttpUser, task, between

file_path = "file_path"

class QuickstartUser(HttpUser):
wait_time = between(3, 10)

@task
def test_compress(self):
data = {
'compress_quality' : 30,
'compress_threshold' : 20
}
files = {
'input_file': ( 'file.jpg', open(file_path, 'rb'), 'image/jpeg'),

}
result = self.client.post("/compress", files=files, data=data)


i am running my fastapi application with following command

gunicorn -k uvicorn.workers.UvicornWorker —-threads 16 chdir app main:app -b 0.0.0.0:7113

I want to remove this Connection Error

ConnectionError(ProtocolError('Connection aborted.', ConnectionResetError(54, 'Connection reset by peer')))

ConnectionError(ProtocolError('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')))
