solve_pnp_generic assertion error

[Craftzman7]

1. Tested on Windows & Linux & MacOS
2. OpenCV installed via package
3. OpenCV version: 4.5.4
4. Rustc version: rustc 1.78.0 (9b00956e5 2024-04-29)

I'm attempting to execute the calib3d::solve_pnp_generic method but it always fails with an assertion error. So far my only lead is that it doesn't like the Vector<Vector<f64>> that I pass in the first two options.
Error:

 ./modules/core/src/matrix_wrap.cpp:72: error: (-215:Assertion failed) 0 <= i && i < (int)vv.size() in function 'getMat_'
 (code: StsAssert, -215)

Code:

let camera_matrix: Vec<f64> = vec![1.5423439978686960e+04, 0.0, 2.5748006057298221e+02, 0.0, 4.4603671037286931e+03, 2.7826697712257112e+02, 0.0, 0.0, 1.0];
let dist_coeffs: Vec<f64> = vec![-6.6209197452352086e+01, 7.2707747669563760e+03, 4.2347679589010436e+00, 7.3656411868892713e-01, -2.3636395586370299e+03];

let fidiucial_size: f64 = 0.1651;
let object_points = vec![
    vec![-fidiucial_size / 2.0, fidiucial_size / 2.0, 0.0],
    vec![fidiucial_size / 2.0, fidiucial_size / 2.0, 0.0],
    vec![fidiucial_size / 2.0, -fidiucial_size / 2.0, 0.0],
    vec![-fidiucial_size / 2.0, -fidiucial_size / 2.0, 0.0],
];

let image_points = tags[0].corners().iter().map(|x| Vector::from_iter(x.iter().map(|y| *y as f64))).collect::<Vector<Vector<f64>>>();

let object_points = object_points.iter().map(|x| Vector::from_iter(x.iter().map(|y| *y as f64))).collect::<Vector<Vector<f64>>>();

let camera_matrix = opencv::core::Mat::from_slice(&camera_matrix).unwrap();

let dist_coeffs = opencv::core::Mat::from_slice(&dist_coeffs).unwrap();

let calc = opencv::calib3d::solve_pnp_generic(
    &object_points,
    &image_points,
    &camera_matrix,
    &dist_coeffs,
    &mut opencv::core::no_array(),
    &mut opencv::core::no_array(),
    false,
    opencv::calib3d::SolvePnPMethod::SOLVEPNP_IPPE_SQUARE,
    &mut opencv::core::no_array(),
    &mut opencv::core::no_array(),
    &mut opencv::core::no_array(),
)?;

Any idea why this is happening?
