Can you share the code for main.toit? I'm curious to see how you try to open the network.

[floitsch]

This was on alpha.75, Artemis 0.5.0.

main
    --supabase_project/string
    --supabase_anon/string
    --device_id/string
    --pin_rx1/int
    --pin_rx2/int?:

  client/supabase.Client? := null
  forwarder1/LogForwarder? := null
  forwarder2/LogForwarder? := null

  while true:
    // Trying to work around https://github.com/toitlang/pkg-http/issues/89
    catch --trace:
      client = supabase.Client.tls
          --host="$(supabase_project).supabase.co"
          --anon=supabase_anon
          --root_certificates=[certificate_roots.BALTIMORE_CYBERTRUST_ROOT]

and Supabase has the following code:

  constructor.tls network/net.Interface?=null
      --host/string
      --anon/string
      --root_certificates/List
      --local_storage/LocalStorage=NoLocalStorage:
    host_ = host
    anon_ = anon

    if not network:
      network = network_to_close_ = net.open

    http_client_ = http.Client.tls network --root_certificates=root_certificates
    local_storage_ = local_storage
    add_finalizer this:: close

[kasperl]

So where do call close on null?

[floitsch]

The close on null was my mistake. However, it led to the program to crash and being restarted immediately (interval=0).
