TypeScript errors.ts file has errors on fresh install and npm run build fails

[Ethan-Guttman]

Steps to Reproduce

• Clone local repository
• Try to compile/build

Observed Behaviour

• Fails with semantic error TS2322:

• Error is located in src/helpers/errors.ts

Expected Behaviour

• succeeds compile on fresh install

Possible Solution

• I have a solution already but I'd like it to get sanity checked
• In same file as error just switch line 14 from
  export type Errors = NonEmptyArray<string>;
  to
  export type Errors = NonEmptyArray<AnyJson>;
  I got it passing all tests and I'll be making a pull request with it soon
