Subject

In the context of my project, I need to add a collection of fields to the 'settings' of a block. The collection must contain at least three items for the form to be valid.
When I go to page-compose to create (or edit) the block and do not meet the given constraint, I notice an error appearing in the debug console, but the error messages are not displayed in the back office (no flash message, the input does not have the 'error' class). However, I observe the expected behavior when I create a shared block.

Minimal repository with the bug

After investigation, this is due to the modification of composer.js when upgrading to version 4.*

Steps to reproduce

I configure my form

public function configureEditForm(FormMapper $form, BlockInterface $block): void
    {
        $form->add('settings', ImmutableArrayType::class, [
            'keys' => [
                ['content', TextareaType::class, [
                    'label' => 'form.title',
                    'translation_domain' => 'SonataBlockBundle',
                ]],
                [
                    'covers',
                    CollectionType::class,
                    [
                        'label' => 'list of cover',
                        'required' => true,
                        'entry_type' => ImmutableArrayType::class,
                        'entry_options' => [
                            'label' => false,
                            'keys' => [
                                [
                                    'label',
                                    TextareaType::class,
                                    [
                                        'label' => 'form.label',
                                        'translation_domain' => 'SonataBlockBundle',
                                        'required' => true,
                                    ],
                                ],
                                [
                                    'description',
                                    TextareaType::class,
                                    [
                                        'label' => 'form.description',
                                        'translation_domain' => 'SonataBlockBundle',
                                        'required' => true,
                                    ],
                                ],
                            ],
                        ],
                        'allow_add' => true,
                        'allow_delete' => true,
                        'delete_empty' => true,
                    ],
                ],
            ],
            'translation_domain' => 'SonataBlockBundle',
        ]);
    }

I add validation rules

public function validate(ErrorElement $errorElement, BlockInterface $block): void
    {
        $errorElement
            ->with('settings[covers]')
                ->addConstraint(new Count(['min' => 3]))
            ->end();
    }

Expected results

Constraint error

Actual results
