Need to use .then({}).catch({}) block in all services while interacting with db

[varunon9]

We thought that if something will break at db level e.g. Error: Duplicate entry '1' for key 'PRIMARY' then it will be automatically caught by controller. But this is not happening. Server is crashing with no logs so need to use catch block in services as well.

An example-

createService: (service) => {
    return new Promise((resolve, reject) => {
      models.service.create(service).then(service => {
        resolve(service.dataValues);
      }).catch(err => {
        reject(err);
      });
    });
  }
