400 Client Error: Bad Request

I’m having trouble loading data.

~\AppData\Roaming\Python\Python39\site-packages\sentinelhub-3.8.0-py3.9.egg\sentinelhub\download\handlers.py in new_download_func(self, request)
     45                 and exception.response.status_code != requests.status_codes.codes.TOO_MANY_REQUESTS
     46             ):
---> 47                 raise DownloadFailedException(
     48                     _create_download_failed_message(exception, request.url), request_exception=exception
     49                 ) from exception

DownloadFailedException: Failed to download from:
with HTTPError:
400 Client Error: Bad Request for url: https://services.sentinel-hub.com/api/v1/batch/process
Server response: "{"status": 400, "reason": "Bad Request", "message": "Access denied - bucket in wrong AWS region or not writable by Sentinel Hub", "code": "COMMON_BAD_PAYLOAD"}"

I’ve tried several times to fix it and it’s configured as required.
I may have missed any part, please advise.


Your returned error indicates one of 2 things:

"Access denied - bucket in wrong AWS region or not writable by Sentinel Hub"

Either your bucket is in the wrong AWS region; Batch Processing API is only deployed in AWS EU (Frankfurt) and AWS US (Oregon)

Or you have not set your bucket policy correctly. I suggest going through the documentation, specifically here to fix your issue.

If you are still having trouble, then let us know.

done but still the same I did as the guide suggested.


There a couple of typos in your bucket policy. Try this:

    "Version": "2012-10-17",
    "Statement": [
            "Sid": "Sentinel Hub permissions",
            "Effect": "Allow",

                "arn:aws:s3::: sentineltongthtest/*"
