Hello all. I am trying to use S3 storage (s3Ninja for "unit test") and I am really messed about how it works. Simple process [image: image.png]
I fetch a simple PDF content and try to post to s3. But in the resulting content, I found the first line : 20000;chunk-signature=c0d176ad5f54df79ca61a1de74d71731f3bf2e92972d7c5ca25f79d83b99b63f I am trying to google this, and I found that it may come from chunk upload. But the file is small, less than 1 Mo. It is also the case with simple text file. I use Wireshark to track traffic, and I found that there is the signature added during the call. Also, I always have an exception saying the signature is not valid : com.amazonaws.SdkClientException: Unable to verify integrity of data upload. Client calculated content hash (contentMD5: RJHSWwvsGtV1rweS3gmThQ== in base 64) didn't match hash (etag: 9a86aae10bb9318d22c3ddea1f93fd07 in hex) calculated by Amazon S3. You may need to delete the data stored in Amazon S3. (metadata.contentMD5: null, md5DigestStream: com.amazonaws.services.s3.internal.MD5DigestCalculatingInputStream@239e8a25, bucketName: renditions, key: 43cc8b40-0f36-4bb4-9ad6-ea079ecbd5a1.pdf) Any idea or input for investigation ?
