magento 2.4.5-p8 “The bucket doesn’t exist” for custom filter

I add new filter using plugin for MagentoFrameworkSearchRequestConfigFilesystemReader

Now sometimes I have error “The bucket doesn’t exist.” for added bucket. After cache flush it works correct.

Due to caching – most of the time the filters are not displayed at all because there was an error when _getItemsData() for the new filter. The worst thing is that I can’t reproduce it locally. Maybe someone has an idea why the error may occure periodically?
