Cannot play YT videos anymore

[Stofl ¶]

I use the beta of the Discord Bot Maker. A few days ago my bot worked just fine, but then the "play" command stopped working for a lot YT videos. Some still work, yet they are the exception.
I use the "play" command to let the bot join the user's voice channel and play the audio of a YT video. It is not only this command and the problem seems to be with the "Play YT video" action.

Does anyone have the same problem? Or knows how to fix it?

I include the raw data for the command:

{
  "name": "play",
  "permissions": "NONE",
  "restriction": "1",
  "_id": "hhyJU",
  "actions": [
    {
      "info": "0",
      "infoIndex": "1",
      "storage": "1",
      "varName": "url",
      "name": "Store Command Params"
    },
    {
      "storage": "1",
      "varName": "vol",
      "changeType": "0",
      "value": "10",
      "name": "Control Variable"
    },
    {
      "info": "0",
      "infoIndex": "2",
      "storage": "1",
      "varName": "vol",
      "name": "Store Command Params"
    },
    {
      "storage": "0",
      "varName": "",
      "name": "Delete Message"
    },
    {
      "channel": "0",
      "varName": "",
      "name": "Join Voice Channel"
    },
    {
      "url": "${tempVars(\"url\")}",
      "seek": "0",
      "volume": "${tempVars(\"vol\")}",
      "passes": "1",
      "bitrate": "",
      "type": "1",
      "name": "Play YouTube Video"
    }
  ]
}

at the bottom at
""url": "${tempVars(\"url\")}",
"seek": "0",
"volume": "${tempVars(\"vol\")}","

remove the \'s in the temp vars, atleast that's what it does for me when i add them with right mouse button
