N8n Form Next Page Multi-Select No Output

[Wayne]

When I have multi select set to true in json in the next page form triggers, on selection and submission here is no output. For example:

[

   {
      "fieldLabel": "Select",
      "fieldType": "dropdown",
      "requiredField": true,
      "fieldOptions": {
        "values": [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
      },
"multiselect": true
   }
]

And the output is with multi select true

[
  {
    "Select": null,
    "submittedAt": "2025-03-23T06:29:36.106-04:00",
    "formMode": "production"
  }
]

However when set to false it works

[
  {
    "Select": "REDACTED",
    "submittedAt": "2025-03-23T06:30:24.989-04:00",
    "formMode": "production"
  }
]

This was working before, so I’m assuming a breaking change with an update?

It looks to be a bug, I am still on 1.81.4 since I read some more bugs.

I rebuild your form trigger setup like below, and can see correct output

You might want to file a bug report on this

I have the same issue. If I set the define form JSON but if I use the fields I have an output.

I fix my issue. I forgot to add “formatDate”: “mm/dd/yyyy” in the date field.
