TypeScript 3.7 optional chaining operator is not supported

[AngusGMorrison]

Hound is throwing up TypeScript parsing errors for the optional chaining operator, ?., which was added in TypeScript 3.7. For example:

wrapper?.update()
// => Parsing error: Expression expected

These errors are not reproduced locally.

Hound is configured to use eslint, and the errors occur using both eslint 6.8.0 and 7.7.0. Locally we run TypeScript through eslint using @typescript-eslint v4.12 (the problem also occurs using v2.33).

eslint:
  enabled: true
  config_file: .eslintrc
  version: 6.8.0

Could this be an issue with Hound TypeScript support, or is there additional configuration required?

@gylaz Hi, are you able to chime in on this one? We are unable to use the optional chaining feature of TS since Hound errors with the following:

We are using the "@typescript-eslint" esling plugin alongside the @typescript-eslint/parser parser. Both of which support optional chaining.

I'm unsure as to where the error is being thrown on Hound's side. Are you using an outdated version of @typescript-eslint?

I'm having the same issue.

@gylaz @josh08h Is there an update on this? Experiencing this still. We're just ignoring the hound warnings, as the code transpiles fine, but it is kinda annoying haha

@AngusGMorrison Did you happen to find a solution for this, I've been hitting this error every so often and I keep ending up at this issue...

@GoudekettingRM hi, we migrated off Hound & went with reviewdog instead
