Environment

1. OS (where OpenCTI server runs): { e.g. Mac OS 10, Windows 10, Ubuntu 16.4, etc. } AWS Fargate
2. OpenCTI version: { e.g. OpenCTI 1.0.2 } 6.4.5

4. Other environment details: n/a

Reproducible Steps

Recently upgraded, saw the above error in the logs, 240x/hour. Corresponds to my load balancer health check interval. Going to switch to the new /healthcheck API, however regardless of what my HTTP / check is doing, the above error appears wrong.

Steps to create the smallest reproducible scenario:

1. { e.g. Run ... }
2. { e.g. Click ... }
3. { e.g. Error ... }

Expected Output

Standard 4xx error

Actual Output

My containers aren't falling over, so probably a 200.

Additional information

Healthcheck configuration:

  health_check {
    enabled             = true
    protocol            = "HTTP"
    healthy_threshold   = 2
    unhealthy_threshold = 10
    timeout             = 15
    interval            = 30
    path                = "/"
    matcher             = "200"
  }
