Cannot read property 'key.filepath' of undefined

[Error - 12:29:44] Request textDocument/definition failed.
  Message: Request textDocument/definition failed with message: Cannot read property 'key.filepath' of undefined
  Code: -32603 

I’m not exactly sure what triggered this, but it happened while trying to autocomplete internal let valet: Val... in the code below:

import Foundation

import PromiseKit
import Valet

open class BioPass {
    enum Error: Swift.Error {
        case notAvailable
        case failedEncodingPassword
        case failedCreatingSAC
        case unhandledKeychainError(OSStatus)
        case unexpectedPasswordData
    }

    let serviceName: String

    internal let valet: Val

    public init(_ serviceName: String = Bundle.main.bundleIdentifier!) {

        if serviceName == "" { fatalError("serviceName cannot be an empty string") }

        self.serviceName = serviceName
    }

Both PromiseKit and Valet are installed as dependencies with Swift Package Manager.

Fixed in 2.3.0

@LinusU good catch! Was actually related to #11 and occured if there is no documentation like in your window.
