Erro no npm start no webservice

Boa noite,

Estou tentando executar o comando npm start e está gerando o erro abaixo:

> api@1.0.0 start C:\Users\piton\source\repos\aluracar-webservice
> node server.js

events.js:183
      throw er; // Unhandled 'error' event
      ^

npm ERR! Failed at the api@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Estou executando esse comando dentro da pasta do webservice e já tentei excluir a pasta node_modules dentro da pasta do webservice e executei npm install e não resolveu.

Queria resolver isso pra prosseguir com o curso.
