I cant open the flow I created in flow designer.

Hi Community,

I’m facing a persistent issue where a specific Flow will not load in Flow Designer. I developed this in one PDI and it was working but then stopped loading the flow , I even migrated it to another pdi using an Update Set. While the Update Set committed successfully, the flow refuses to open (infinite loading/blank screen) in that pdi also.

What I’ve tried so far:

• Ran cache.do multiple times.

• Repaired the Flow Designer plugin.

could be because of version mismatch between Workflow studio plugin and Flow Designer plugin

check this KB which talks about this

Unable to Open Flows in Workflow Studio -> repair Workflow Studio Plugin which updates Flow Designer Plugin and then logout and login again

The practical fix is to not keep troubleshooting that same flow, but instead recover it. Go to the working PDI (or wherever it last opened correctly), export the flow as XML (sys_hub_flow + related records) or duplicate it, and then re-import or recreate it in the target instance. If you don’t have a clean version, try opening related records like sys_hub_flow_version or actions used in the flow — sometimes one broken action causes the whole designer to hang, and removing/replacing that action fixes it. In many cases, though, the fastest solution is to rebuild the flow (copy steps manually) because once the definition is corrupted, Flow Designer won’t render it.
