Code Sample, a minimal, complete, and verifiable piece of code

# Your code here
from satpy.scene import Scene
from satpy.resample import get_area_def
from datetime import datetime
from glob import glob
from pyresample.utils import get_area_def

FILES = glob("/home/griffith/GIS/testData/*DAT")
scn = Scene(sensor='ahi',start_time=datetime(2018, 4, 14, 2, 00),end_time=datetime(2018, 4, 14, 2, 10),filenames=FILES,reader='ahi_hsd')
print(scn.available_dataset_names())
band = "B03"
scn.load([band])

area_id = 'japan_vol'
x_size = 392
y_size = 449
area_extent =  (-196090.1123778188, -222697.93829216747, 196090.11237782123, 226337.63024405806)
projection = '+proj=laea +lat_0=31.914 +lon_0=130.89 +ellps=WGS84'
description = "japan_vol"
proj_id = 'laea_130.89_31.914'


areadef = get_area_def(area_id, description, proj_id, projection,x_size, y_size, area_extent)
local_scene = scn.resample(areadef)
local_scene.save_datasets(writer='simple_image')

#### Problem description
If I use other bands, there is no error. Error only occurred in Band 3
I know error occurred at local_scene = scn.resample(areadef)
but not sure about how to fix it, could someone shed a light on this issue?

#### Expected Output
