Unable to resolve types of columns in clean project #1071
Description
Issue
I'm testing out sequelize-typescript for data access on a brand new next.js project. However I can't get the type resolution to work at all. I suspect it has something todo with the reflection, so I've modified a bit of the error message to contain more information.
Its probably some mistake I did, but I'm now at a loss of what to do next.
The error I'm getting is
Error: Specified type of property 'name' on target '[object SequelizeInstance:_Project]' getting type 'undefined'
cannot be automatically resolved to a sequelize data type. Please
define the data type manually

The model class is defined as follows
import { Table, Column, Model, HasMany, HasOne } from "sequelize-typescript";
@Table
export default class Project extends Model {
@Column
name: string;
}Here is my sequelize setup:
const sequelize = new Sequelize({
database: 'some_db',
dialect: 'sqlite',
username: 'root',
password: '',
storage: ':memory:',
models: [__dirname + '/models']
})my tsconfig.json

Please note I've extended the error message to include more values of the variables in the executing code.
