Error when trying to open workflow "Content is not allowed in prolog"

Hello, I am receiving the following error when trying to open a workflow that I used just yesterday: Unable to parse xml: line=2: Content is not allowed in prolog.
dtd: URI=null

So far, I’ve tried restarting my computer, restarting knime, and switching workspaces. This is very concerning, as I have been working on this workflow for weeks. Any help will be greatly appreciated!

It sounds like there is a corrupted file in your workflow tree. If you want to export it and attach the export to this thread, we could see which file it is - or you could look yourself at .project and workflow.knime at the root level, and then each node directory (and subdirectories) have .xml files in them as well.

That all being said, unless the file is trivially corrupted, the prognosis for recovery of the workflow isn’t great.



Hopefully you do have some backup?
