400: The resource submitted could not be validated.

[websmyth]

I’ve connected a formset to MailChimp but logbook is showing the following error on submission:

400: The resource submitted could not be validated. For field-specific details, see the 'errors' array.

The issue only appears when I add the formset to MailChimp (under Form on the settings page), and emails aren’t passed to the corresponding mailing list.

I’ve tried removing the validation from the formset, but that didn’t work.

Formset

store: false
honeypot: email_address
fields:
  user_email:
    display: Email
    validate: email|required
columns:
  - user_email

I bet it's because it assumes the email field is email

Thanks, Erin. I’ve changed the formset (and corresponding inputs etc) to:

store: false
honeypot: email_address
fields:
  email:
    display: Email
    validate: email|required
columns:
  - email

The error has changed to 400: Your merge fields were invalid.

I haven’t set merge fields as there’s only one and it looks from the docs that email is assumed and auto-merged. I’ve also tried adding merge fields and it’s the same result.

Any ideas? Seems odd.

Let's see your mailchimp.yaml

[websmyth]

mailchimp_key: *************************
add_new_users: true
user_disable_opt_in: false
user_check_permission: false
user_mailchimp_list_id: ************
forms:
  -
    mailchimp_list_id: *************
    disable_opt_in: false
    form: mailing_list
    check_permission: false

Let's see the list (audience) settings:

And can you please check your Statamic log to see the there are more details there?

[websmyth]

The Statamic logs don’t reveal anything more, unfortunately: [2019-10-29 16:07:12] dev.ERROR: 400: Your merge fields were invalid.

[edalzell]

You’ve got required fields you don’t have in your fieldset, FNAME and LNAME.

EIther add them or don’t make them required

[websmyth]

Ah, of course. Thanks for your help – I’ll ask my client to change that.

Please re-open if issue persists after making those changes.
