Unhandled request 'message' at this path

I want to get list audioRoom but I got this error, can someone help? I am new to Janus

First I create session and keep sessionID, then I use this request:

listRoom localhost/janus {
  janus: 'message',
  plugin: 'janus.plugin.audiobridge',
  session_id: 5737318986044880,
  transaction: 'JZqiMZhRPs0f',
  body: { request: 'list' }
}

Then I got this error:

result {
  janus: 'error',
  session_id: 5737318986044880,
  transaction: 'JZqiMZhRPs0f',
  error: { code: 457, reason: "Unhandled request 'message' at this path" }
}

In the end what is the cause of the error?
