Sequelize error : cannot find property "startYear" of undefined - node.js

Question

I am using sequelize cli and got each migration file for each model generated, I am trying to generate all the tables with a single migration file as they are dependent on each other, but I am keep getting this error
cannot find property startYear of undefined
Also, I need a tutorial on how to change models in sequelize using sequelize cli.

Use a validate function in the options argument:
{
validate: {
endYearIsAtLeastStartYear() {
if (this.endYear < this.startYear) {
throw new Error('End year must be equal to or higher than start year')
}
}
}
