Guide to configuring a not null property in Typescript Sequelize:

Hello there! I am trying to figure out how to set a not null property using TypeScript Sequelize. I have tried using the @NotNull decorator, but unfortunately it does not seem to be working. The errors I am encountering are as follows:

Validation error: Warning "notNull" validation has been deprecated in favor of Schema based "allowNull"\

I have already set the property as not null in my MySQL scheme.
