sequelize “findbyid” is not a function but apparently “findAll” is

Question

I am getting a very strange problem with sequelize, When I try to call the function findAll it works fine (same for create and destroy), but when I try to call function \"findBy

Answer 1

Directly pass value.

Question.findByPk(question_id).then(question => {
            return res.status(200).json({
                question: question
           });
}).catch(err => {
     console.log(err);
});

Answer 2

the team of sequelize was deleting this function and replced it by a new function is

findByPk

like this

// search for known ids
Project.findByPk(123).then(project => {
  // project will be an instance of Project and stores the content of the table entry
  // with id 123. if such an entry is not defined you will get null
})

Answer 3

With Sequelize v5, findById() was replaced by findByPk(). Replace findById using findByPk and everything should work fine. You can find query doc here
