@orlando3,

What input is it expecting?  What input did you give it? What's the trigger?

Bump

Im facing the same issue. I have the flow contained in a scoped application containing a "main" flow that has an "application" trigger for a certain catalog item. The flow itself creates several catalog tasks on which the flow that causes pretty much the same error as OP described (although on sc_task).

I first suspected that domain separation causes the issue (the instance and flow is domain separated), but I haven't found an answer yet.

@orlando3 Could you please share the screenshot of your flow along with the trigger conditions. This might help to share further inputs.

I was able to identify the root cause of the issue. It is due to an recent upgrade to Utah (my customer skipped Tokyo, so we upgraded from San Diego).

What was leading me to the solution was this article: https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0997550
Basically, the flow trigger depends on a record in the sys_json_chunk table. However this table was replaced with sys_flow_context_chunk.
(Reference: https://docs.servicenow.com/bundle/tokyo-application-development/page/administer/flow-designer/conce...)
My original problem was that flow was created/modified on a utah/tokyo instance while the target instance was still on san diego. Therefore the target instance was expecting a mapping on via sys_json_chunk, while my dev-instance was delivering a flow trigger mapping via sys_flow_context_chunk.
