Hello,
Any solution for this error, because I am facing the same error "flush operation is not support in read mode"

as an error might be caused by several issues, we will strongly advise you to send logs to our support team as advised by andy previously.

Already done and the super support is : we don't support any more SFTP !! No comment.

Just an update regarding this case: it looks like an SFTP misconfiguration, the storage is in read-only mode. Sorry, but you would need to tweak things on your side.
And yes, we can only provide limited troubleshooting steps regarding FTP configurations, since we consider it a legacy protocol.
