Access Landsat 8 data in Sentinelhub

I try to perform a simple WcsRequest to retrieve Landsat 8 images from Sentinelhub via Python. The Request finds images but the arrays contain only 0 values. I just used code from the official example at https://sentinelhub-py.readthedocs.io/en/latest/examples/ogc_request.html
Here is my request:

‘’’
INSTANCE_ID = ‘your Instance id’ # In case you put instance ID into configuration file you can leave this unchanged

if INSTANCE_ID:
config = SHConfig()
config.instance_id = INSTANCE_ID
else:
config = None

betsiboka_coords_wgs84 = [46.16, -16.15, 46.51, -15.58]
betsiboka_bbox = BBox(bbox=betsiboka_coords_wgs84, crs=CRS.WGS84)![configuration|689x238]

l8_request = WcsRequest(
data_collection=DataCollection.LANDSAT8,
layer=‘1_TRUE_COLOR’,
bbox=betsiboka_bbox,
time=(‘2017-08-20’,‘2017-09-20’),
resx=‘30m’,
resy=‘30m’,
config=config,
maxcc=0.5,
)

l8_data = l8_request.get_data()
‘’’

Here is my configuration in sentinelhub

Hi @bibiberlin,

For now please add an additional parameter time_difference=dt.timedelta(seconds=1). The timedelta should be at least 1 second, but it can be more. The following request should therefore work

l8_request = WcsRequest(
    data_collection=DataCollection.LANDSAT8,
    layer=‘1_TRUE_COLOR’,
    bbox=betsiboka_bbox,
    time=(‘2017-08-20’,‘2017-09-20’),
    resx=‘30m’,
    resy=‘30m’,
    config=config,
    maxcc=0.5,
    time_difference=dt.timedelta(seconds=1)
)

The issue happened due to the recent changes in Sentinel Hub service. It will be fixed in the next release of sentinelhub-py package.
