Winston logger does not output Error (generate by cli)

[psi-4ward]

The default index.ts create by feathers cli catches unhandled promises and logs the error using winston which does not output the error nor the stack

plain-js testcase:

const { createLogger, format, transports } = require('winston');

const logger = createLogger({
  level: 'info',
  format: format.combine(format.splat(), format.simple()),
  transports: [new transports.Console()]
})

process.on('unhandledRejection', function(reason, p) {
  console.error('[console.error] Unhandled Rejection at: Promise ', reason, p);
});

process.on(
  'unhandledRejection',
  (reason, p) =>
  logger.error('[WINSTON] Unhandled Rejection at: Promise ', p, reason)
);

(async function() {
  await new Promise((res, rej) => rej(new Error('fuubar')));
})();

output
