How do I have a flow run with empty interface form links and there's a combine text node?

[michaelraspuzzi]

I have a flow with 6 entry points from a form.

I have error shields around each node after the form: ex. web scrape, pdf extract info.

I want to combine all of the information into one place, but the combine text doesn’t run when a form field is entry (ex. 5/6 or 2/6 are submitted).

How do I make this run more robust?

• I tried passthrough on error but that didn’t work for error shields
• I tried filtering and routing node but they only work when there is something to pass through.
• So I’m guessing I need to update or change the combine text node somehow - maybe join paths - or use a different approach?

Here’s the run where it doesn’t say there’s an error but it stops at the combine text node because of empty values -

Hey @michaelraspuzzi! If you’re reporting an issue with a flow or an error in a run, please include the run link and make sure it’s shareable so we can take a look.

1. Find your run link on the history page. Format: https://www.gumloop.com/pipeline?run_id={{your_run_id}}&workbook_id={{workbook_id}}

2. Make it shareable by clicking “Share” → ‘Anyone with the link can view’ in the top-left corner of the flow screen.
   

3. Provide details about the issue—more context helps us troubleshoot faster.

You can find your run history here: https://www.gumloop.com/history

Hey @michaelraspuzzi – Yes, exactly. A `Join Paths node would work perfectly here. Its purpose is to merge outputs from any given node, whether it’s the success or error branch, or any mutually exclusive branches.

For example, the join paths node can take both the success and error outputs of a node and continue down to the combined text node, even if inputs are empty.

I’ve set that up in the workflow below. Feel free to make a copy and test it out. Let me know if that works.

Wasay, thanks for the help!

It was at first non intuitive because Gummie kept recommending 1) filter or 2) routing nodes, but I couldn’t get those to work.

Noted We’ll improve Gummie’s logic here!
