[Question] can't use nimword in proc

[ITwrx]

hi,
I'm having trouble trying to use nimword's isValidPassword in Guildenstern.
I'm trying: let compareResult = password.isValidPassword(registeredUser.password) (inside a try block) and i'm still getting the dreaded:

Error: type mismatch
Expression: newHttpServer(handlePost)
  [1] handlePost: proc (){.gcsafe.}

Expected one of (first mismatch at [position]):
[1] proc newHttpServer(onrequestcallback: proc () {.gcsafe, nimcall, raises: [].};
                   loglevel = LogLevel.WARN; parserequestline = true;
                   hascontent = true): HttpServer

Any ideas about what is going on?
Thanks

maybe because nimword's encodedHash variable is not marked as a {.threadvar.} for thread safety?

Your handlePost is missing both the nimcall pragma and doesn't explicitly state that it never raises an Exception (that's what raises:[] means). It should get those implicitly, but you can't know that if there's something you missed that would make your proc not have those.

Note that isValidPassword states: {.raises: {UnknownAlgorithmError, ValueError, Pbkdf2Error, SodiumError, Exception}.} =
So unless you catch all of those and in the end also the general "Exception" this can not work. This is where a minimal example for confirmation would help 😛

@PhilippMDoerner thanks for your answer. I responded in the nimword issue.
