     CypressError: `cy.request()` failed on:

The response we received from your web server was:

  > 500: Internal Server Error

This was considered a failure because the status code was not `2xx` or `3xx`.

If you do not want status codes to cause failures pass the option: `failOnStatusCode: false`

Because this error occurred during a `before each` hook we are skipping the remaining tests in the current suite: `Testes em rotas com usuário...`

Boa tardeO erro mostrado na imagem indica que o teste do Cypress está falhando porque a requisição para http://localhost:8080/auth/login retorna 500 Internal Server Error.
A mensagem principal é:

Internal server error: The "password" argument must be of type string or an instance of ArrayBuffer, Buffer, TypedArray, or DataView. Received undefined

Isso significa que, no backend, o campo password não está chegando corretamente — provavelmente está vindo undefined.
Esse erro ocorre por dois motivos comuns:

Variáveis de ambiente não configuradas no GitHub Actions
O teste depende de dados como e-mail e senha (clinica@gmail.com, 4321), mas no GitHub Actions essas variáveis podem não estar definidas. Verifique se estão sendo passadas corretamente no arquivo .github/workflows/...yml, por exemplo:

env:
  EMAIL: clinica@gmail.com
  PASSWORD: 4321

E no teste, use-as assim:

cy.request({
  method: 'POST',
  url: 'http://localhost:8080/auth/login',
  body: {
    email: Cypress.env('EMAIL'),
    password: Cypress.env('PASSWORD')
  }
})

Servidor backend não inicializado antes do teste
Se o backend (localhost:8080) não estiver rodando no ambiente do GitHub Actions, a requisição vai falhar.
Nesse caso, é preciso garantir que o serviço seja iniciado antes de rodar o Cypress, por exemplo:

services:
  api:
    image: node:18
    working_dir: /app
    volumes:
      - .:/app
    command: npm start
    ports:
      - 8080:8080
