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];
