Has anyone tried out this tutorial [Automate with Custom Dataprep Filters &amp; Operations | Tutorial](https://dev.epicgames.com/community/learning/tutorials/XjZP/unreal-engine-automate-with-custom-dataprep-filters-operations) ? For some reason I cannot get the metadata combo filter to work. Using unreal 5.2 and I have manage to dig out and use the meta data values with the normal metadata value block.

Does your custom datasmith fetcher compile, do you have any warnings?  
Did you create a fetcher and copy code from the example?

Maybe some boxes not plugged properly after the copy?

It compiles without errors. I just downloaded the file a copied it into the project.

To me it seems that it misses some output functions, the fetch box at the far right.  
There should be one (the current one), with both boolean ticked that should be called if all succeed  
There should be another one, with Out Fetch succeed ticked and Return Value unticked, that should be plugged to every “branch” false condition.  
I reported it to the creator.
