larvae queue worker Trying to get property 'id' of non-object

I switch from the sync driver to the database driver for the queue and I been getting this error ErrorException Trying to get property 'id' of non-object. I have no idea where this error is happening since everything works with the sync driver. I tried to find some solutions to this problem but I am unable to find anything that leads me in the right direction.

I know what the error means but it just does not make since that I am getting this error.
