On Form Submission Error Cannot read properties of undefined (reading 'name')

Hi everyone,

I’m running version 1.98.2 on n8n cloud.

Here’s additional info

  • n8nVersion: 1.98.2
  • platform: docker (cloud)
  • nodeJsVersion: 22.16.0
  • database: sqlite

My workflow was running just fine, then suddenly started throwing this error whenever I tried inputting information in the on form submission trigger:

Cannot read properties of undefined (reading 'name')

Anybody else run into this issue? I’ve deleted the form and rebuilt it, restarted my workspace a couple times, all my fields have names…not sure what else I could check.
