Below is my terraform script. I have set up the necessary forwarding rules and target http proxies. Also the backend services exist. I am able to access all paths under /images/*, however, I can’t access the paths under /videos/*. From the script, the dafault backend service is backend-lb-prod which is the backend service where the path /images/* exists. I switched the default backend service to backend-lb, I could now access /videos/* but not /images/*. 

resource "google_compute_url_map" "url-map-be" {
  name            = "${var.platform_name}-url-map-be-prod"
  default_service = "${google_compute_backend_service.backend-lb-prod.self_link}"

  host_rule {
    hosts        = ["${var.backend_address_name}"]
    path_matcher = "allpaths"
  }

  path_matcher {
    name            = "allpaths"
    default_service = "${google_compute_backend_service.backend-lb-prod.self_link}"

    path_rule {
      paths   = [“/images"]
      service = "${google_compute_backend_service.backend-lb-prod.self_link}"
    }  

    path_rule {
      paths   = [“/images/*"]
      service = "${google_compute_backend_service.backend-lb-prod.self_link}"
    } 

    path_rule {
      paths   = ["/videos"]
      service = "${google_compute_backend_service.backend-lb.self_link}"
    }  

    path_rule {
      paths   = ["/videos/*"]
      service = "${google_compute_backend_service.backend-lb.self_link}"
    }

  }
}

When I run the tests for the url map on the google console, this is the error I get

Invalid value for field 'resource': ''. Test failure: Expect URL ‘*.*.*.*/videos/go' 
to map to service ‘***93-BACKEND_SERVICE-**-backend-lb', but actually mapped to 
'***93-BACKEND_SERVICE-**-backend-lb-prod’.

This is how google_compute_url_map in the terraform documentation is illustrated. What am I missing in this case.

update

I have included the /videos and /images paths and the error above is gone. However, from the logs of the application, the traffic is still sent through the default backend service.

Hope this helps any other person. Under the host_rule the hosts was initially an IP address. I also had it changed to a domain name but it still sent all traffic to the default backend service. I changed it to * and it now works as expected. Also to be noted, the paths that are not of the default backend service take a few minutes before they can be accessed.

host_rule {
  hosts        = ["*"]
  path_matcher = "allpaths"
}
