I was experimenting with attributes API in Magento and accidentally modified the attribute that I didn't want to modify and which seems to be important in for product form. It is links_purchased_separately.

My version of Magento is 2.3.1

Now, when I try to open any product, I get only the exception message and stack:

Exception #0 (Magento\Framework\Exception\LocalizedException): The "formElement" configuration parameter is required for the "links_purchased_separately" field.

Full stack trace:

Exception #0 (Magento\Framework\Exception\LocalizedException): The "formElement" configuration parameter is required for the "links_purchased_separately" field.

  • What change did you make there? – Ravi Soni Jun 26 '19 at 13:41
  • I overwritten this attribute with mine, so I have entirely different attribute now and I don't now how this attribute was configured before. I have the access to Magento 2.2.7 but I cannot see such attribute in there. – wmioduszewski Jun 26 '19 at 13:45
  • If you want to revert then you can check here how this attribute was created by default here: /var/www/html/magento227/vendor/magento/module-downloadable/Setup/InstallData.php – Ravi Soni Jun 26 '19 at 13:50
  • OR for same case, you can refer this solution also: magento.stackexchange.com/questions/204420/… – Ravi Soni Jun 26 '19 at 13:58
  • Thanks! Didn't know what you meant by /var/www/html/magento227/vendor/magento/module-downloadable/Setup/InstallData.php but it brought me to github.com/magento/magento2/blob/2.3-develop/app/code/Magento/… where I found the defaults for this attribute and thanks to that - I resolved my problem. Thank you! :) – wmioduszewski Jun 26 '19 at 14:12

You can find default behavior here.

\vendor\magento\module-downloadable\Setup\Patch\Data\InstallDownloadableAttributes.php

/** @var EavSetup $eavSetup */
$eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);
/**
 * Add attributes to the eav/attribute table
 */
$eavSetup->addAttribute(
    \Magento\Catalog\Model\Product::ENTITY,
    'links_purchased_separately',
    [
        'type' => 'int',
        'backend' => '',
        'frontend' => '',
        'label' => 'Links can be purchased separately',
        'input' => '',
        'class' => '',
        'source' => '',
        'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
        'visible' => false,
        'required' => true,
        'user_defined' => false,
        'default' => '',
        'searchable' => false,
        'filterable' => false,
        'comparable' => false,
        'visible_on_front' => false,
        'unique' => false,
        'apply_to' => 'downloadable',
        'used_in_product_listing' => true
    ]
);

Might this will help to resolve your issue.
