The 2026 Drupal Business Survey is open. Your response will help shape the future of the Drupal business ecosystem.I have the latest stable version of paragraphs installed and the 8.x-3.x version of the field group module installed. I'm getting the following ajax error when trying to create a paragraph via the admin.
TypeError: Argument 2 passed to field_group_field_group_form_process_build_alter() must implement interface Drupal\Core\Form\FormStateInterface, null given, called in /srv/bindings/code/web/core/lib/Drupal/Core/Extension/ModuleHandler.php on line 539 in field_group_field_group_form_process_build_alter() (line 429 of /srv/bindings/code/web/modules/contrib/field_group/field_group.module)

Looks like there has been a lot of movement on this branch in the past 5 days, so I decided to revert back to a commit hash before those changes and it fixes this issue. Has anyone else run into this?

justin2pin commentedI just got the same error. What commit did you roll back to?
Comment #3
justin2pin commentedA recent commit made $form_state and $form parameters optional here:
function field_group_form_process(array &$element, FormStateInterface $form_state = NULL, array &$form = []) {But not in the subsequently called hook_field_group_form_process_build, here:
function field_group_field_group_form_process_build_alter(array &$element, FormStateInterface $form_state, array &$form) {Attached patch makes the $form_state and $form parameters optional for hook_field_group_form_process_build and solves this issue in my environment.
Comment #4
justin2pin commentedApologies, I should have looked closer at that last patch. This should be the correct one.
Comment #5
rivimey@justin2pin I encountered the same problem, and decided to fix it by making the form_state arg nullable:
This is a php 7.1 feature, which is works for me on 7.2 but I'm not sure if it's generally ok at present. Php 7.0 has already reached official end-of-life, and is due to be dropped from D8 imminently.
I'm not sure if your patch:
is equivalent to mine in this regard or not.
In some ways I'd prefer that the type was left out of the php signature for the moment.
Comment #6
rivimeyTweak issue description length, make 'pre'.
Comment #7
jsheffers commentedThe patch listed here won't apply for me with the latest dev commit. @justin2pinThis patch does apply and it works.
However the fields in my groups are not grouping properly anymore.Edit: Looks like I need the paragraphs patch here:
https://www.drupal.org/files/issues/2907094_7_field_group_support.patch
All works fine now.
Comment #8
sime@jsheffers isn't that patch in Paragraphs 8.x-1.7 already? Which version of Paragraphs are you using?
Comment #9
jsheffers commented@sime we're using 8.x-1.7, didn't seem to be working before the patch...
Comment #10
simeThanks. I'll try and verify this - there is a pending RC I believe and a regression with paragraphs is not ideal :P
Comment #11
kumkum29 commentedOk for me with the patch #4.
Do you think include this correction in the dev version?
thanks.
Comment #13
nils.destoop commentedThx for the patch. I committed it to dev
Comment #14
nils.destoop commentedI temp removed the typehint, as drupal 8.6 still supports php 5.6
