Use SLURM to run a Mathematica file which contains parallel comp. commands?

I am trying to use slrum to run a Mathematica file which contains some parallel commands. If I launch the frontend on the server then I can easily perform the computation with paralleltable[] etc but some how when I use sbatch to run the file it keeps giving me following error,

--- SLURM job-script output ---
Launching kernels...

Get::noopen: Cannot open CloudObjectLoader`. 

Any idea guys?

Thank you! -
