Merge not returning data in test mode

[geggeri]

Bug Description

A merge node does not return any items when testing a node after the merge. The merge uses the append option, but one of the appended branches never reaches the merge. When running the full workflow it works as expected, but when testing from within a node (after the merge), the merge does not return any items

To Reproduce

Create a workflow with 3 branches. Let the first branch end without result and let the two other branches return something.

Each of the branches should be connected to a merge node using the append option.

Expected behavior

To work as it does on a full run.

Hi @geggeri,

I've been trying to recreate this but I can't seem to get it to happen.
Can you clarify your reproduction of the issue please?

Here's what I've tried:

Branches 2 and 3 set some data but branch 1 doesn't.

In the NOOP node I get the following:

Am I missing something in my workflow? Thanks!

Hej Marc I cannot recreate it anymore. When I reported it I was able to recreate it within my workflow, but I just tried again and now I cant. Might have just been a UI / browser glitch. Sorry for the inconvenience Have a mice day Mads tirs. 7. jan. 2025, 13.15 skrev Marc Littlemore ***@***.***>:
