I am using Download/Upload from list node in order to download images from a list of URL. Although it generally works, it sometimes downloads empty image files without warning.
Is it possible that the URI is failing because of the semicolon tacked on at the end, or is that just a result of you pasting the URI from KNIME to the forum?
If that’s not the issue, it would be helpful for you to upload a workflow that reliably reproduces the problem.
