Problem with HTTP IN Node - DataCloneError: DataCloneError: function () { [native code] } could not be cloned. #80

Hi,

When using the Put Object node in a flow involving HTTP IN and HTTP Response nodes, the presence of non-serializable objects like msg.res or msg.req causes the node to throw the error:

DataCloneError: DataCloneError: function () { [native code] } could not be cloned.

For example, a flow like [HTTP IN] -> [Function 1] -> [Put Object] -> [Function 2] -> [HTTP Response] fails to work as expected.

This makes it difficult to use the node in HTTP-based flows. It would be great if the node could handle such objects gracefully or provide guidance for working around this issue.

Thanks!

After some further investigations the problem arrises because of the structuredClone-function used on the input message. I did a test to remove that dependency on the Put Object-function in this branch https://github.com/fasblom/node-red-contrib-generic-s3/tree/Removal-of-structuredClone-of-Put-Object and it seems to work. But there might be other good reasons why the structuredClone is there in the first place that I don't kow about.
