METIS fails to partition a 297 nodes graph into 64 parts : bisect a graph with 0 vertices

So like said in the title, I’m trying to partition a graph using METIS. More precisely, I have a mesh that has 297 elements, so those are the 297 nodes of the graph and I want to partition it into 64 parts for distributing the workload on 64 different MPI processes. So the nodes/elements are weighted by their computational cost, and for simplicity one can say it is the number of nodes within each element.
