Issue

first, net is right，and pp.runpp(net, max_iteration=10, tolerance_mva=1e-5, numba=True) is successful！
but，I tried to design a state estimation example，as bellow：
def state_estimation(self, request):
bb_case_id = request.GET.get("bb_case_id")
net_json = bb_service.get_json_format_net(bb_case_id=bb_case_id)
net = pp.from_json_string(net_json)
# 假设 df 是你的 DataFrame 对象
print(net.bus)
for index, row in net.bus.iterrows():
if row['dt_vn_kv'] is None or row['dt_vn_kv'] <0.1:
print(str(index)+':'+row['name']+':'+row['bus_name'])
else:
pp.create_measurement(net, "v", "bus",row['dt_vn_kv']/row['vn_kv'], 0.004, index)

    success = est.estimate(net, init="flat")
    print(success)
    return DetailResponse(data=None, msg="成功")

I tried to running，but report error。
