TypeScript: The 'propertyName' property does not exist on the 'Function' type


TypeScript compiler is giving me an error on the following code example although the generated JavaScript on https://www.typescriptlang.org/play/ works as intended

The error is: error TS2339: Property 'tableName' does not exist on type 'Function'.

class ActiveRecord {
    static tableName(): string { // override this
        return "active_record";

    static findOne(): any {
        return 'Finding a record on table: ' + this.tableName();

    save(): void {
        console.log('Saving record to table: ' + this.constructor.tableName());

class MyModel extends ActiveRecord {
    static tableName(): string {
        return "my_model";

let x = new MyModel();
x.save(); // "Saving record on table: my_model"
console.log(MyModel.findOne()); // "Finding a record on table: my_model"

Is there is anything I can do to fix this error?

To fix the TypeScript error and still get the intended behavior (not using ActiveRecord.tableName()) you can cast the constructor to a typeof ActiveRecord

(this.constructor as typeof ActiveRecord).tableName())
