Hi @Swapnil_Ghorpade, if this is search-ui related I recommend you log an issue directly on the repository: [https://github.com/elastic/search-ui/issues](https://github.com/elastic/search-ui/issues).

Please be sure to provide more information when you do so. The version number you are using, the browser, the full stack trace, and steps to reproduce.
