A specific node connection does not persist over workbook saves

[hpb]

Here’s a short video showing the issue I’m having. I connect the Doc Reader node to the Ask AI node and save the workbook. But when I close and reopen the node, the connection between them is gone. How do I fix this? Here is the workbook link.

Hey @hpb! 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.

I’ve seen this a number of times too and it doesn’t seem to be consistent.

Hey @kevinbstout @hpb, the reason you’re seeing this issue is because the connection between nodes won’t persist unless the output from the upstream node is actually being used in the downstream node.

Make sure to drag the output badge from the upstream node (like Doc Reader) into a field inside the connected node (like Ask AI). If the connection is only visual and the output isn’t used, it will automatically be removed when the workbook is saved.

@Rithen_Gumloop Thank you! This fixed it. I had two Google Doc readers connected to the AI node and I was sure that I was using inputs from them both. On further debugging, I realized that I was only using one. After ensuring that outputs from both the readers are being used, I now the see the connection persist.
