Get All Actors Of Class with Tag issue!! Help me thanks!

I want to use Get All Actors Of Class with Tag to move camera to tagged actor, but when I compiler Blueprint the errors and warning show below:
Get All Actors Of Class with Tag was pruned because its Exec pin is not connected, the connected value is not available and will instead be read as default

The current value of the ’ Array ’ pin is invalid: Array inputs (like ‘Target Array’) must have an input wired into them (try connecting a MakeArray node).

You need to connect get …tag
