Blank flow execution since upgrade to Zurich patch 7

ericgilmore · Tuesday

Since upgrading to Zurich patch 7 I've been unable to display my flow executions. This is all I see whenever a open ANY flow execution now.

I've tried:

repairing plugins
clearing cache
copying and simplifying flows
cancelling stale flows (Dev/Test)
displaying OOTB system flows

Nothing has worked so far. Yes, I've also contacted SN support and the one suggestion I got was concerning the logic in ONE of my flows.
But this is affecting EVERY flow.

Has anyone else run into this? How did you fix it?

After working with ServiceNow support, and much testing I've come to the answer on this particular issue. As it turns out I used "Go back to" actions in this flow, and others. After advice offered by SN support, I refactored the flow in question removing all "Go back to" actions, instead using "Do the following...Until" actions. This seems to have cleared up the issue of the blank flow execution tabs.

Additional...

The root cause of the issue is in step 37 of the “Example” flow. The Go back to logic is not configured correctly, which is causing the failure.

You can only add Go back to flow logic within certain portions of a flow.
 • The Go back to flow logic must be within a branch of a parent flow logic block.
 ◦ Then branch of If, Else If, or Else flow logic
 ◦ Answer branch of Make a decision flow logic
 ◦ Catch branch of Try flow logic
 • The Go back to flow logic must be outside of the Error handler section.

This is the official documentation:

...And now I've just confirmed that this became an issue for me after the upgrade to Zurich patch 7. So I'll be refactoring several flows to remove all "Go back to" actions.

Fabulous.
