@bryglen, there is a way to solve this, did you prefer @Macbenach and me make a PR?

[bryglen]

this is a known issue on 7.2, as of now no support for 7.2

@bryglen dude, plz upgrade your composer.json at least 6.++, see reference https://github.com/sendgrid/sendgrid-php/releases, you library are to old, plz make the update.

Hello @bryglen what you think about this snippet

  public function getHeadersJson() {
    if ($this->getHeaders() == NULL) {
     return "{}";
    }

    if (count($this->getHeaders()) <= 0) {
     return "{}";
    }
    return json_encode($this->getHeaders(), JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP);
  }

Maybe exist some better code but it seems to solve the problem in php 7.2, i test it in PHP 7.2 and 7.0
