Hi!

I am using EO-Learn and would like to construct an averaged histogram of a bounding box, therefore I need to loop over many FIS Requests. When I do I seem to be getting an issue with something like “TOO_MANY_REQUEST”… Is it possible to fix this? I am using the month free trial at sentinel-hub at this moment.

Can you help me?

More detailed, when running:

histogram_request = FisRequest(

layer = …,

geometry_list = …,

time = exact_date,

resolution = ‘10m’,

data_source = DataSource.SENTINEL2_L2A,

image_format=MimeType.TIFF_d8,

custom_url_params = {CustomUrlParam.EVALSCRIPT: eval_script},

data_folder = ‘…’

)

histogram_request.get_data(save_data=True, redownload = False, raise_download_errors = True)

I get the following error message;

…\sentinelhub\data_request.py in _execute_data_download(self, data_filter, redownload, max_threads, raise_download_errors, decode_data)

179 client = self.download_client_class(redownload=redownload, raise_download_errors=raise_download_errors)
