@britepencil. Hi Scott. Thanks for posting. I am a little confused. I have tested EFL on my Joomla 3.9 test site, and I have not encountered any issues or notice. Further, I don’t have any code that calls JModuleHelper::getModuleById() directly.
Do you have any PHP error logs regarding the error you have posted? Usually, the error log will specify the file and line number where the problem is. You can send me your error logs via email.
