Can I get thread event body?

[przepompownia]

I try to use a special tab (per thread at the moment) to control the current debug session. My first approach is adding a callback running after get started thread event from the adapter. I have

dap.listeners.after['event_thread']['dap-tab'] = function(session, body)
  vim.notify('Thread started', vim.inspect(session), vim.inspect(body))
end

From the log I got

[ DEBUG ] 2022-02-20T18:47:10Z+0100 ] ...dap-ui-test/pack/bundle/opt/nvim-dap/lua/dap/session.lua:561 ] {
  body = {
    category = "console",
    output = "<- threadEvent\nThreadEvent {\n  seq: 0,\n  type: 'event',\n  event: 'thread',\n  body: { reason: 'sta
rted', threadId: 1 }\n}\n\n"
  },
  event = "output",
  seq = 26,
  type = "event"
}
[ DEBUG ] 2022-02-20T18:47:10Z+0100 ] ...dap-ui-test/pack/bundle/opt/nvim-dap/lua/dap/session.lua:561 ] {
  body = {
    reason = "started",
    threadId = 1
  },
  event = "thread",
  seq = 27,
  type = "event"
}

No body is printed, only Thread started. Should I expect the body too in this way?

It's a typo (comma instead of ..)... Listener works as expected.
