Based on your provided .log file, the error is l301 which is for basis set. It doesn't say 'grad...' error, correct me if I'm wrong.
I think, you may want to redefine your basis set, for instance, you are applying lanl2dz for all atoms while, generally, lanl2dz is used for metals. You can use GEN or GENECP basis set to define mixed basis set.
