FYI for future users searching this, another reason for this error can be if you accidentally clear your timeline after the pavlovia_init. Something like:

/* init connection with pavlovia.org */
var pavlovia_init = '{'
  type: "pavlovia",
  command: "init"
'}';
timeline.push(pavlovia_init);

var timeline = [] // this is a mistake and removes the pavlovia init

to fix it ensure that pavlovia_init is not cleared from the timeline
