Cannot read property 'headersSent' of undefined

Estou fazendo um projeto com express, node e sequelize e esse erro apareceu no console e eu não tenho ideia de como arrumar

C:\Users\Joice\documents\TCC\node_modules\finalhandler\index.js:256
  return typeof res.headersSent !== 'boolean'
                    ^
