Problems with copying from one space to another

We are using Alpakka S3 in our backend to copy a file from one Space to another Space. Unfortunately we get the following error:

[error] (run-main-0) akka.stream.alpakka.s3.S3Exception: (Status code: 400 Bad Request, Code: InvalidPart, RequestId: tx00000000000016cd6af-0060d482e1-15da959a-fra1b, Resource: )

We do not use any special settings. With other cloud providers and with a self-hosted Minio, copying from one bucket to another bucket works without problems. Is there anything special to consider with Digitalocean spaces ? Do I have to provide special headers ?

Thank you and best regards
