If you are using 3dsmax split render with Vray and Render Elements activated, then you will get this error. It is due to 3dsmax split render does not save Vray Render Elements into strips.
To avoid this error, simply disabled Vray Framebuffer, and switch back to 3dsmax Standard Max Framebuffer. Re-submit the render task again then it should run smooth.
