What did you do?

Hello! I've deployed successfully evolution api v2.3.1 to AWS ECS.

When I create an instance and try to scan the QR Code, nothing happens. I've got it to show as connected sometimes but the inside the whatsapp app it should app as syncing forever.

This is how I'm deploying my container

export const service = new sst.aws.Service("EvolutionService", {
  cluster,
  link: [postgres, redis],
  loadBalancer: {
    rules: [{ listen: "443/https", forward: "8080/http" }],
    domain,
  },
  containers: [
    {
      environment: {
        SERVER_URL: `https://${domain?.name}`,
        DATABASE_URL,
        DATABASE_CONNECTION_URI: DATABASE_URL,
        DATABASE_PROVIDER: "postgresql",
        CACHE_REDIS_ENABLED: "true",
        EVOAI_ENABLED: "true",
        CACHE_REDIS_URI: REDIS_URL,
        AUTHENTICATION_API_KEY: authenticationApiKey.value,
        LOG_LEVEL: "ERROR,WARN,DEBUG,INFO,LOG,VERBOSE,DARK,WEBHOOKS,WEBSOCKET",
        LOG_COLOR: "true",
        LOG_BAILEYS: "error",
        DEL_INSTANCE: "false",
      },
      name: "EvolutionContainer",
      image: "evoapicloud/evolution-api:v2.3.1",
      cpu: "0.25 vCPU",
      memory: "0.5 GB",
    },
  ],
});

And this are some of the logs i've gathered

Bom dia

Tambem estou com erro em instancias novas que estou criando.
So consigo enviar mensagem pelo n8n utilizando uma instancia ja criada.

"404 - {"status":404,"error":"Not Found","response":{"message":["Cannot POST /manager/message/sendText/Efluxo_comercial"]}}"

[teovillanueva]

This is happening both in v2.3.0 and v2.3.1.

[aherrh02]

Any solution for this? I am using v2.2.3 and CONFIG_SESSION_PHONE_VERSION=2.3000.1025110696 after trying with newer versions and different CONFIG_SESSION_PHONE_VERSION even leaving it empty
