Cannot set object metadata

[e-dorigatti]

Hello, my objects are created with the wrong content-type and I'd like to change that. The code runs fine and gives no errors, still the metadata is not changed. Here's my code, note that setAsPublicRead works and keys are indeed publicly accessible.

case Some(key) =>
          key.setAsPublicRead()

          key.metadata.setContentType("text/plain")

          val meta = key.getObjectMetadata
          meta.setContentType("text/plain")

          val userMeta = new java.util.HashMap[String, String]
          userMeta.put("test-key", "test-value")
          meta.setUserMetadata(userMeta)

          key.setObjectMetadata(meta)
