When a user with a user ID longer than 40 characters tries to export data from list view of any table and clicks on "Download", a blank page is presented and no file is downloaded.
Applicable to all releases.
The sys_created_by fields on all tables in ServiceNow has a max length of 40 characters. Due to this, the sys_created_by value on the sys_poll record has a truncated value of the user's userID causing an OOB Access control rule (ACL) check to fail when it checks if the sys_created_by value of the sys_poll record is same as the current user's userID.
Since the OOB ACL is failing and causing this issue, comment out the script in the ACL to resolve this issue.
