ValueError: Invalid dtype for argument 'v_colors'. Expected 'f' but got 'u' in _mesh_io.py using TrackedArrays

I get ValueError: Invalid dtype for argument 'v_colors'. Expected 'f' but got 'u' when calling pcu.save_mesh_vf, specifically here

point-cloud-utils/point_cloud_utils/_mesh_io.py

Line 291 in 0fcf6c9

save_mesh_internal(filename,

with both v and f of

point-cloud-utils/point_cloud_utils/_mesh_io.py

Line 483 in 0fcf6c9

def save_mesh_vf(filename, v, f, dtype=np.float32):

being a trimesh.caching.TrackedArray (Subclass of numpy.ndarray) of shapes (n_v, 3) and (n_f, 3) and dtypes dtype("float64") and dtype("int64"), respectively.

Do you have any idea what might be causing this?

I'm using point-cloud-utils 0.31.0 and trimesh 4.6.2.

Thank you for helping
