@naumansigma thanks for your reply but this issue is coming when we download this extension from magento market place and when we download this extension from git then it is working fine.

Hi @sumeetmagento, Im facing this error just now after trying to uninstall this extension. Have you any links to uninstall steps. Ive removed the extension, removed the SDK composer package, removed the Facebook table in the DB, Upgraded the DB, Compiled DI, Indexed and Cleared caches but Im still getting the error when loading the products list in the backend.
