Hi,

I am getting XAmzContentSHA256Mismatch when trying to upload an image via the Spaces API.

Uploading a text/plain works fine, but I am really struggling with image/png.

Using postman, and adding the image in the body as form-data.

Sha256 generated with digest.

I've found that DigitalOcean Spaces does not like signed payloads, which is the default when using things like the AWS PHP SDK v3.

So as well as setting "endpoint", also set "signature_version" to "v4-unsigned-body".
