Getting ValueError: Shape mismatch Error when running OPF

[Azier1010]

I am receiving the following error when running an OPF
ValueError: shape mismatch: value array of shape (32,) could not be broadcast to indexing result of shape (16,2)

This is for a 15 bus system, the gencost array looks like this:

ppc["gencost"] = array([
[1, 0, 0, 2, 86., 1462., 430, 7310],
[1, 0, 0, 2, 86., 1204., 430, 6020],
[1, 0, 0, 2, 85., 1955., 425, 9775],
[1, 0, 0, 2, 85., 1445., 425, 7225],
[1, 0, 0, 2, 73., 1168., 365, 5840],
[1, 0, 0, 2, 73., 2920., 365, 14600],
[1, 0, 0, 2, 73., 1971., 365, 9855],
[1, 0, 0, 2, 79.8, 2872.8, 399, 14364],
[1, 0, 0, 2, 79.8, 1436.4, 399, 7182],

[1, 0, 0, 2, 79.8, 2872.8, 399, 14364],
[1, 0, 0, 2, 79.8, 2234.4, 399, 11172],
[1, 0, 0, 2, 80., 1520., 400, 7600],
[1, 0, 0, 2, 80., 1440., 400, 7200],
[1, 0, 0, 2, 81.4, 1221., 407, 6105],
[1, 0, 0, 2, 81.4, 3093.2, 407, 15466]
])
