How to implement bulk update with sequelize?

Question

I have tried here but I'm not getting correct answer this code will update only one record but I have to update multiple records at a time with different ids and I supposed to pass different ids as an endpoint to an API.

async function bulkupdate(req,res){

    var i;
    let successCount =0; 
    let errorCount = 0;
    var student = req.body;
    var id = req.params.id;

    const schema = {
        name : {type : "string" , optional : false , max :"100"},
        sem : {type : "number" , optional  : false },
        branch :{type : "string" , optional:false,max:"100"}
    
    }
    for(i=0;i<student.length;i++){
        const v = new validator();
        var result1 = await  v.validate(student[i] , schema);
        if(result1 === true){
            var result = await models.Student.update(student[i],{where :{id:id}});
            successCount++;
             
        }else{
            errorCount++
            return res.send({result1,errorCount,successCount})
            
            
        }
    }
    
    res.status(200).json({        
        successCount:successCount,
        errorCount:errorCount,  
    });
  }

It updates one record because the value of id is the always the same, if the request body includes the student id then you can use something similar to this

var result = await models.Student.update(student[i],{where :{id: student[i].id}});
