ts-node: New TS errors after updating to v6.0.0

Since I updated, I have been getting a lot of new TS errors that I haven’t gotten before. When I run my tests in v5.0.1 they all pass and everything runs fine.

  Default
    ✓ should throw InvalidArgumentException if value does not match property type
    ✓ should attach a DefaultAnnotation to the decorated property
    ✓ should return the specified default value if initial value is null or undefined

  Description
    ✓ should attach a DescriptionAnnotation to the decorated properties

  Entity
    ✓ should attach an EntityAnnotation to the decorated class

  AcceptValidator
    ✓ should throw an InvalidArgumentException if it is not constructed with an array
    ✓ should throw an InvalidArgumentException if it is constructed with an empty array
    ✓ should fail validation if the passed in value is not in the accepted values array
    ✓ should pass validation if the passed in value is in the accepted values array

  Accept
    ✓ should attach an AcceptValidator to the decorated properties metadata

  ElementTypeValidator
    ✓ should should throw an InvalidArgumentException if a function is not passed in to constructor
    ✓ should should throw an InvalidArgumentException if the value to validate is not an Array
    ✓ should fail validation if the type of value does not match the type with which the validator was constructed
    ✓ should fail validation when value is a primitive and does not match the type with which the validator was constructed
    ✓ should pass validation if the type of value does match the type with which the validator was constructed
    ✓ should pass validation when value is a primitive and does match the type with which the validator was constructed

  ElementType
    ✓ should throw an UnsupportedOperationException if the decorated property is not an Array type
    ✓ should attach an ElementTypeValidator to the decorated property's metadata

  RequiredValidator
    ✓ should fail validation if value is null or undefined
    ✓ should pass validation if value is not null and not undefined

  Required
    ✓ should attach a RequiredValidator to the decorated property's metadata

  TypeValidator
    ✓ should should throw an InvalidArgumentException if a function is not passed in to constructor
    ✓ should fail validation if the type of value does not match the type with which the validator was constructed
    ✓ should fail validation when value is a primitive and does not match the type with which the validator was constructed
    ✓ should pass validation if the type of value does match the type with which the validator was constructed
    ✓ should pass validation when value is a primitive of the type with which the validator was constructed
    ✓ should return true if value is null or undefined

  Type
    ✓ should attach a TypeValidator to the decorated property's metadata

  validateEntity
    ✓ should run validators on entity
    ✓ should run validators on any nested entities
    ✓ should throw an error for each validator that fails
    ✓ should throw errors for all nested validators at once

  setClassProperties
    ✓ should throw an InvalidArgumentException if passed null or undefined for the properties argument
    ✓ should throw an InvalidArgumentException if passed null or undefined for the classPrototype argument
    ✓ should assign passed in properties to the passed in class prototype

Here are the results when I run it with v6.0.0

I did try to fix those specific errors but when I do, I just get more and on things that are definitely typed. In order to just try to get around the implicit any errors, I just disabled that check in my tsconfig.json. That takes care of the implicit any errors, but that just results in one that makes even less sense.

Here is the code that it says those properties aren’t defined in.

export abstract class Exception {
    public message: string;
    public name: string;

    constructor(message: string) {
        const ctor = (this as Object).constructor;

        Error.captureStackTrace(this, ctor);

        this.message = message;
        this.name = ctor.name;
    }
}

So they are definitely defined and also the line numbers don’t match up either. For the sake of completeness, here is the config for ts-node for mocha and how it is called.

/* config/mocha.config.js */
require('source-map-support/register');
const tsNode = require('ts-node');
tsNode.register({
    compilerOptions: {
        target: 'es5',
        module: 'commonjs',
        sourceMap: true
    } 
});

and the npm script that runs it,

"mocha": "nyc mocha -C --reporter spec config/mocha.config.js \"./src/**/*.spec.ts\""
