priorityConfigurationOverride
An alternative priority list of locations that's included with a game session placement request. When provided, the list overrides a queue's location order list for this game session placement request only. The list might include Amazon Web Services Regions, local zones, and custom locations (for Anywhere fleets). The fallback strategy tells Amazon GameLift Servers what action to take (if any) in the event that it failed to place a new game session.
