Hello everyone,
We’re finalizing a voice AI workflow where a webhook from our AI platform (Vogent) triggers one of two paths.
The Problem: The AI is supposed to extract an email address and pass it to our workflow. Sometimes, the extraction fails, and it sends a null value for the email. Our n8n workflow execution log shows “Succeeded,” but the final “Send Email” node obviously fails to send the email because the “To” field is empty.
Is there a community-recommended best practice or standard pattern for handling these kinds of “silent” node failures? We’re considering adding an IF node after the trigger to check for empty/null data, but we wanted to ask if there’s a more elegant or robust way to build resilient workflows that can gracefully handle and report on incomplete input data.
Thanks for any insights!
hey @Quikle25 welcome to n8n community!
I think if condition is reliable option!
Thanks Moosa, think so too. Hope it works
Yes it will but you should optimize ai agent for extracting email.
Btw why it is not returning email address?
So I am using a Voice agent built via Vogent and set up function calling that flows through the workflow. The data comes in but does not pass through my switch node.
Think the main issues were my expressions not aligning with incoming data from Webhook.
Well if you could share your workflow we might be able to help more.
