Errors when trying to put a call on hold

I implemented that solution, but it made no difference. The outside phone does not respond. I can't answer, or hold. Am I doing this wrong?

So i dug deeper and put some logs in the ringcentral Client.php, here they are.

When i run this code i get this for the output.

The Constructor for a GuzzleHttp Request does not take an array for the body.

eventually this array ends up here and this is where the exception is thrown.

Im going to try checking ahead of time if its an array and just pass in an empty string.

Thanks for your time.

Now I pay closer attention to your first code sample, why do you pass an empty array to the post request that does not take any body?

Simply remove it.

$path = "/account/accountId/telephony/sessions/[telephonySessionId]/parties/[partyId]/hold";
  try{
      $resp = $platform->post($path);
      ...
  }catch (ApiException $ex){
      print_r("error");
      print_r($ex->getMessage());
  }
