Could you please create a repository where you reproduce this issue?

Which version of express-routes-mapper are you using?
Which node version are you using?
How does your routes file look like?

"express-routes-mapper": "^1.0.4",
I think the problem comes from express, the solution was to bind the "this" in the constructor:

constructor(model, qcolumns) {
    this.model = model.query();
    this.qcolumns = qcolumns;
    //PATCH: _this_ is undefined using express and express-routes-mapper
    this.get = this.get.bind(this);
    this.set = this.set.bind(this);
    this.getByID = this.getByID.bind(this);
    this.update = this.update.bind(this);
    this.delete = this.delete.bind(this);
  }
