Unable to start the server because Sequelize V6 is not yet supported by sequelize-typescript

[avtarnanrey]

This starter repository is not working anymore because of a recent major release of Sequelize V6. We are getting the following error:

TSError: ⨯ Unable to compile TypeScript:
src/models/index.model.ts(25,22): error TS2769: No overload matches this call.
  The last overload gave the following error.
    Type 'typeof User' is not assignable to type 'string | ModelCtor<Model<any, any>>'.
      Type 'typeof User' is not assignable to type 'ModelCtor<Model<any, any>>'.
        Type 'typeof User' is not assignable to type 'typeof Model'.
          Construct signature return types 'User' and 'Model<T, T2>' are incompatible.
            The types of '_attributes' are incompatible between these types.
              Type 'User' is not assignable to type 'T'.
                'T' could be instantiated with an arbitrary type which could be unrelated to 'User'.

sequelize-typescript is not yet upgraded to support Sequelize V6.
I think this one is the WIP: sequelize/sequelize-typescript#804

The workaround for this right now is to downgrade the last v5 version of "sequelize": "^5.22.2",.
