Hi,
Using python 3.9 and sentinelhub 3.8.0, ogc requests fail when multiple dates are available and a custom eval script is provided in the request, see basic example below:
from sentinelhub import CRS, BBox, DataCollection, MimeType, SHConfig
from sentinelhub.api.ogc import OgcRequest
from sentinelhub.constants import CustomUrlParam, ServiceType
config = SHConfig()
config.instance_id = INSTANCE_ID
evalscript = """
//VERSION=3
function setup() {
return {
input: [{
bands: ["B02", "B03", "B04"]
}],
output: {
bands: 3
}
};
}
function evaluatePixel(sample) {
return [sample.B04, sample.B03, sample.B02];
}
"""
ogc_request = OgcRequest(
layer="S2-L1C",
bbox=BBox(bbox=[46.16, -16.15, 46.51, -15.58], crs=CRS.WGS84),
data_collection=DataCollection.SENTINEL2_L1C,
time=("2019-12-15", "2019-12-25"),
service_type=ServiceType.WMS,
size_x=512,
size_y=856,
config=config,
image_format=MimeType.TIFF,
custom_url_params={
CustomUrlParam.EVALSCRIPT: evalscript
}
)
ogc_request.get_data()
This results in the following error:
DownloadFailedException Traceback (most recent call last)

Server response: "Failed to evaluate script!

}
^"
- The code above works if only a single date is available in the time interval, e.g. time=“2019-12-15”
- Furthermore, it also works, if the exact same eval script is configured directly in the layer instead.
- Finally, it works using python 3.7 and sentinelhub 3.0.0
Do you have any idea, what causes this?
Best regards
Lasse
