Hi. I'm trying to update the 'Only run if' for a waterfall, but keep getting the error 'Failed to update waterfall'. Why? How can I solve it?

To resolve the "Failed to update waterfall" error when updating 'Only run if' conditions: Access Full Configuration: ** Navigate to Edit Column > Full Configuration to modify waterfall settings properly ** Don't try to modify conditions through basic settings - use the full configuration menu Check Run Condition Setup: ** Ensure your conditional formula is properly structured using the Conditional formula generator ** Verify you're using correct syntax with dynamic variables (use / to select columns) and comparison operators Review Condition Logic: ** Make sure your run conditions account for all possible inputs and edge cases ** Consider if the condition might be preventing the waterfall from updating due to unmet criteria If you continue experiencing issues after checking these areas, please request human assistance by clicking on "Talk to a person" for further troubleshooting.

Hi Nicolas, I'm seeing the phone waterfall was able to find most but not all phone contacts.
Please let me know how else I can help here! Gabe

I'm trying to update the 'Only run if', nothing to do with the results I got

I want to make sure I'm understanding the issue correctly. Do you mind providing a little more context on what you want to change the Only run to? The waterfall has already run so it wouldn't take effect for these but happy to help for the future additions!

((!{{Dropcontact Phone}} || {{Check Phone Line Type & Status}}?.status?.toLowerCase() !== "valid") && (!{{People Data Labs Phone 1}} || {{Status 1}}?.toLowerCase() !== "valid") && (!{{People Data Labs Phone 2}} || {{Status 2}}?.toLowerCase() !== "valid") && (!{{People Data Labs Phone 3}} || {{Status 3}}?.toLowerCase() !== "valid"))

In the future, I only want it to run when it meets the above

I was able to add a different formula, so I assume the error is with the formula I shared with you. That formula was created by the AI whithin Clay, so not sure what the issue is

Is your new formula working? Recreating the formula allowed the whole column to refresh which also could've affected the outcome.

Hey Gabe. It worked with a different formula, but that one was just a placeholder I used to test if the issue was that

I want to use my original formula, and that one doesn't work

Nicolas - Sorry for this, it looks like we've got a bug on our hands. I've escalated this to our engineering team to help look into it. We'll follow up here as soon as we know more!

Hi Nicolas, It looks like this formula causes an infinite loop. The phone columns you're trying to reference for the "only run if" are actually outputs from that waterfall. This formula tell the waterfall: "only run this waterfall if this waterfall's output is x." This breaks the formula as it doesn't know what to do. I've attached the dependency graph view below for your review. Please let me know if you're still having other issues and how else I can help here! Gabe
