call is coming from Request at let encoded = q.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)

Not really sure what to do about this, since it's probably a swift bug. Does anyone have a reference to a reported bug or a workaround?

The query string that is crashing :

▿ 5 elements
  ▿ 0 : 2 elements
    - key : "legal_entity[type]"
    - value : "company"
  ▿ 1 : 2 elements
    - key : "managed"
    - value : true
  ▿ 2 : 2 elements
    - key : "metadata[id]"
    - value : "28"
  ▿ 3 : 2 elements
    - key : "email"
    - value : "xxx@xxxx.xxx"
  ▿ 4 : 2 elements
    - key : "country"
    - value : "US"

which version of the engine package are you using?

[hhanesand]

1.3.12

[tanner0101]

Hmm. Definitely seems like a Swift bug. Try upgrading to Swift 3.1 if you can. If it continues to be an issue we can look into workarounds / using vapor/core methods instead.
