Here first question of mine.
Now i added custom attribute to my customer following this code

InstallData.php

<?php



namespace KtAddBonusSetup;



 use MagentoCustomerModelCustomer;

 use MagentoCustomerModelCustomer;

 use MagentoCustomerSetupCustomerSetupFactory;

 use MagentoEavModelEntityAttributeSetFactory as AttributeSetFactory;

 use MagentoFrameworkSetupInstallDataInterface;

 use MagentoCustomerModelCustomer;

 use MagentoFrameworkSetupModuleContextInterface;

 use MagentoFrameworkSetupModuleDataSetupInterface;





class InstallData implements InstallDataInterface

{



const BONUS_ATTRIBUTE_CODE = 'customer_bonus';





/**

 * @var CustomerSetupFactory

 */

private $customerSetupFactory;

/**

 * @var AttributeSetFactory

 */

private $attributeSetFactory;





public function __construct(CustomerSetupFactory $customerSetupFactory,

                            AttributeSetFactory $attributeSetFactory)

{



    $this->customerSetupFactory = $customerSetupFactory;

    $this->attributeSetFactory = $attributeSetFactory;

}





/**

 * Installs data for a module

 *

 * @param ModuleDataSetupInterface $setup

 * @param ModuleContextInterface $context

 * @return void

 */

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)

{

    $setup->startSetup();



    $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);



    $customerEntity = $customerSetup->getEavConfig()->getEntityType('customer');

    $attributeSetId = $customerEntity->getDefaultAttributeSetId();

    $attributeSet = $this->attributeSetFactory->create();

    $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);



    $customerSetup->addAttribute( Customer::ENTITY, self::BONUS_ATTRIBUTE_CODE, [

        'type' => 'int',

        'label' => 'Customer Bonus',

        'input' => 'text',

        'required' => false,

        'visible' => true,

        'user_defined' => true,

        'system' => false,

    ]);



    $attribute = $customerSetup->getEavConfig()->getAttribute( Customer::ENTITY, self::BONUS_ATTRIBUTE_CODE)

        ->addData([

            'attribute_set_id' => $attributeSetId,

            'attribute_group_id' => $attributeGroupId,

            'used_in_forms'=>['adminhtml_customer']

        ]);





    $attribute->save();

    $setup->endSetup();



}

}

And now i need Plugin which will change custom attribute value to 1000.

this is what i have:

etcdi.xml

<?xml version="1.0"?>

 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

 <type name="MagentoCustomerApiCustomerRepositoryInterface">

<plugin name="bonusPlugin" type="KtAddbonusBonusPlugin"/>

</type>

</config>

PluginBonusPlugin.php

<?php



namespace KtAddBonusPlugin;







use KtAddBonusSetupInstallData;

use MagentoCustomerApiCustomerRepositoryInterface;

use MagentoCustomerApiDataCustomerInterface;



class BonusPlugin

{

 public function beforeSave(CustomerRepositoryInterface $customerRepository,

                           CustomerInterface $customer)

{

    $customer->setCustomAttribute(InstallData::BONUS_ATTRIBUTE_CODE,1000);

 }



}

when i press "Create An Account" it just reset password fields in registration form and remains on this page, with the "we cant save Customer" error.
How i can create this plugin? And what i did wrong?

Try like this,

etcdi.xml

<type name="MagentoCustomerModelAccountManagement">

   <plugin name="bonusPlugin" sortOrder="10" type="KtAddbonusPluginBonusPlugin"/>

</type>

PluginBonusPlugin.php

<?php



namespace KtAddbonusPlugin;





use MagentoCustomerApiDataCustomerInterface;

use MagentoCustomerModelAccountManagement;



class BonusPlugin

{

    public function beforeCreateAccountWithPasswordHash(AccountManagement $subject,CustomerInterface $customer, $hash, $redirectUrl)

    {

        $customer->setCustomerBonus("1000");

        return [$customer, $hash, $redirectUrl];

    }

}
