Re: [analyzer-discuss] await context.currentSession.getResolvedUnit( path ); returns empty result

[Konstantin Shcheglov]

  `SomeResolvedUnitResult` as its name implies, is just some, not fully specified result.

  There are a few implementations of it, returned depending on whether the arguments or state are valid or invalid.

  What you are looking for is `ResolvedUnitResult`, which is returned when the result is valid.

  So, check the result of `resolveFile`, e.g.

  if (result is ResolvedUnitResult) { ... }

Why is this happening?
