[error][ignored] Failed to capture tab: image readback failed

When I use window task schedule to trigger macro without user login , the macro contains script visualAssert, there are error as below
[error][ignored] Failed to capture tab: image readback failed

Does this mean that no user account is logged in? Web browsers like Chrome and Firefox do not support this, thus many strange things happens. A user must be logged in. You can use the Windows autologin feature for this.
