Workflow edits no longer saving, error message "Can't save dataflow - unknown exception"

[Tomcat3]

We have at least a half-dozen Workflows which have been under development for months. Recently we have not been able to save updates. They pass all validation tests and then appear to hang on "Saving changes".

This is a PPU workspace, been running fine for the past year. No other diagnostics are available. Error is repeatable with every affected Workflow, small & large. Error has been repeatable for at least the past four days.

Update ：

The fix is deployed, Since different clusters have different deployment times, check for yourself later to see if the fix is complete.

You might want to try this, just in case.  Go to Project options and click on "Allow combining data from multiple sources..."

 Might not help but worth a try.

I have not received an update on this problem, but it looks like it is gone or less prevalent.

Having the same issue - how do we escalate this?

Have you had any success recently? I have a feeling "...internal icm..." issues, whatever "icm" means, are fast-tracked and kept under the radar. No complaint if its fixed. I always tell my clients "....its not a bug if I fix it before you see it..."
