Hello @SergeLavrentyev,

Thanks for the report and collaboration!

We have tried to reproduce the issue in the latest development branch i.e. 2.4-develop, but for us, the issue is not reproducible.

As per the main description, first, we tried to create a custom integration test with @magentoConfigFixture example/path/test 1, but the issue is not reproducible for us. Please refer to the below screenshot for reference:

But then we checked the error you mentioned in the main description, and according to the error, it seems you are facing an issue is in api- functional test. So then we tried to reproduce it api-functional test following the below steps:

1. Edit file

   magento2/dev/tests/api-functional/testsuite/Magento/Catalog/Api/AttributeSetManagementTest.php

   Line 35 in a4cf5e6

   public function testCreate()

2. Add @magentoConfigFixture example/path/test 1 for testCreate method
3. Ran the test via the below command:
   ../../../vendor/bin/phpunit -c ../../../dev/tests/api-functional/phpunit_rest.xml --filter 'testCreate' ../../../dev/tests/api-functional/testsuite/Magento/Catalog/Api/AttributeSetManagementTest.php

The test was completed successfully. Please refer to the below screenshot:

Please let us know if we have missed anything.

Thanks
