Keep running into this error. Any ideas why? It's breaking the workflow with Gnuplot...

That is just an inaccurate error message. The real problem is that you had bad gnuplot syntax i.e. title="blah blah" instead of title "blah blah", to which gnuplot complained "invalid expression". What the kernel sees is a plot command, so it prepares an image file for gnuplot to print to; , gnuplot draws nothing because of the bad syntax and the kernel reacts to something wrong but not sure what it is.

I will add this case to what could have gone wrong.
