c# package, problem to send files to IONOS S3 with objects locks

[MarcAndreSG]

Hello everyone,

I have a problem with the C# package.
I keep getting the same error message when transferring data to the IONOS S3 storage:

"Content-MD5 HTTP header is required for Put Object requests with Object Lock parameters"

I have set the MD5 content:

And yet I still get this error message

A colleague pointed it out to me,
that the name that was transferred

“X-Amz-Meta-Content-Md5”

would be!?

I told him no, I use “Content-Md5”

Then I debugged the code:

You see the name is an other, as I set.
Monio does not use the name given, but uses his own.

My question is why is that?
Is that correct?
Is this a bug?

I don't know much about this package, but Content-MD5 is added if WithRetentionConfiguration has been set.

I don't know if there is any other way of setting it, so I will leave it here for someone more deeply into this package to look at it.
