crash when calling req.closeWait()

[moin110x]

Hi, please forgive me if i misunderstood something really basic that makes this issue; i am trying to do a simple get request and the application is crashing

proc getipv4*(): string =
    var session = createSession(true)
    # let address = initTAddress("api.ipify.org:443")
    let address = resolveTAddress("api.ipify.org",443.Port,Domain.AF_INET)[0]
    let ha = getAddress(address, HttpClientScheme.Secure, "/")
    var req = HttpClientRequestRef.new(session, ha, MethodGet)
    let response = waitFor fetch(req)
    if response.status == 200:
        let data = cast[string](response.data)
        result = data
    else:
        result = "fail"

    waitFor(req.closeWait()) #crash happens at this line with msg  'Future operation cancelled!'
    waitFor(session.closeWait())

log:
