Private Key and Certificate Files Not Attaching When Specific Extensions Are WhitelistedDescriptionWhen a customer whitelists some specific extensions for the ServiceNow instance using the "List of file extensions" property, private key file, and certificate files are not attached to the records, and the error message "The uploaded file type is not permitted; allowed types are xlsx, doc, xls, docx" appears on the UI. This is because these files do not have any extensions, and using the "List of file extensions" property, the customer allowed only some specific extensions to attach to the instance.
