Tzdata.ReleaseUpdater argument error

Hello,

Erlang/OTP 22 [erts-10.5] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1]

I've been getting an error every time my project tries to update the timezone database, for a few weeks now.

** (ArgumentError) argument error

I've run into a dead end debugging this as the Tzdata.HTTPClient.Hackney module uses the callback system I'm not familiar with.

I also don't see any similar issues created, so I'm thinking this is some sort of configuration error on my part. Do you perhaps have an idea why this is erroring?

This happens to me too, but intermittently. I have the same versions of Erlang, Elixir, tzdata and hackney as @dabaer.

[Jcambass]

Can confirm that this happens.

I had the same issue and I solved starting hackney before tzdata.

def application do
    [
     ...,
      extra_applications: [:logger, :runtime_tools, :hackney, :tzdata]
    ]
  end
