The Problem is that in Kubernetes (which your configuration looks like) the rooms/receivers are always prefixed with the namespace and the name of config (namespace/config_name/receiver).
You can use the query parameter room_name with the dispatch endpoint and set it to the receiver name, that should fix the error.

For example:

apiVersion: monitoring.coreos.com/v1alpha1
kind: AlertmanagerConfig
metadata:
  name: alertas
  namespace: cattle-monitoring-system
spec:
  receivers:
    - name: alertas
      webhookConfigs:
        - url: http://caalert-calert:6000/dispatch?room_name=alertas
  route:
    groupBy:
      - job
    groupInterval: 5m
    groupWait: 30s
    receiver: alertas
    repeatInterval: 12h
