Confirmed issue!

The argument is not in terraform registry, but it exists on the API as pathMatchers[].routeRules[].customErrorResponsePolicy.

When trying to use a custom_error_response_policy inside a route_rules block it returns the message: Unexpected block: Blocks of type "custom_error_response_policy" are not expected here. Example:

resource "google_compute_http_health_check" "http_hc_20100" {
  provider           = google-beta
  name               = "http-hc-20100"
  request_path       = "/"
  check_interval_sec = 1
  timeout_sec        = 1
}

resource "google_compute_backend_service" "backend_service_20100" {
  provider    = google-beta
  name        = "backend-service-20100"
  port_name   = "http"
  protocol    = "HTTP"
  timeout_sec = 10
  load_balancing_scheme = "EXTERNAL_MANAGED"
  health_checks = [google_compute_http_health_check.http_hc_20100.id]
