I have deployed ejabberd on a aws server with a certain IP and hostname as ejabberd.myname.test

specifications:

  • ejabberd version: 19.09.57
  • Erlang version: Erlang (SMP,ASYNC_THREADS,HIPE) (BEAM) emulator version 10.5.6
  • OS: Centos
  • Installed from: source

From my NodeJS server I am trying to hit the ejabberd API to issue token for a certain jid:

return` rp({
  uri: `${EJABBERD_URL}/api/oauth_issue_token`,
  method: 'POST',
  headers: {
    'X-Admin': true,
    'Authorization': this.adminAuth,
  },
  body: {
    jid,
    ttl: 3600,
    scopes: "sasl_auth"
  },
  json: true,
})

where:

EJABBERD_URL : ejabberd.myname.test:5280

this.adminAuth: "Basic " + new Buffer(EJABBERD_ADMIN_USERNAME + ":" + EJABBERD_ADMIN_PASSWORD).toString("base64");

There is a case_clause error thrown upon hitting this API:

    [info] (<0.558.0>) Accepted connection [::ffff:192.168.0.100]:54170 -> [::ffff:192.168.0.200]:5280
