Iterate trough ofMesh vertices

Hello everyone,

I’m drawing some meshes from polylines using tessellateToMesh().
After doing that, I want to iterate to all the vertices and set their color according to some calculated value (i.e.: the distance to the next vertex), but I’m constantly getting what I think is a bad pointer error:

Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)

the loop I’m using is this one:

       ofMesh mesh;
        tess.tessellateToMesh(polyline, (ofPolyWindingMode) 1, mesh);
        
        for(unsigned int j = 0; j < mesh.getVertices().size(); j++) {
            mesh.setColor(j, ofColor(0.1,0.5,0.9));
        }

Am I doing something clearly wrong that i just can’t see?
Thanks.
