Fix type error in AsyncHandler.qml
Summary | 概述: There is a type error in AsyncHandler, because the current code assigns undefined
to a Connection
's target
, which expects a QtObject. This commit assigns null
instead of undefined
to it, eliminating the type error.
Type | 类型: fix
Test Plan | 测试计划: Change a user's power level. Verify that the message
qrc:/AsyncHandler.qml:18:5: Unable to assign [undefined] to QObject*
does not appear in the logs.
