Results is invalid.

Error message

Results is invalid.

What it means

ResourceGroupCollection.GetResourceNames fills a caller-supplied List<string> with the full names of all resources aggregated in the collection. It throws GameFrameworkException("Results is invalid.") when the results list is null, since the list is used directly as the output buffer.

Solutions

  1. Allocate the list first: var results = new List<string>(); collection.GetResourceNames(results);
  2. Initialize list fields/variables before passing them to any GetResourceNames overload.
  3. Catch GameFrameworkException around the call if the list origin is uncertain.

Example fix

// before
List<string> names = null;
collection.GetResourceNames(names);
// after
List<string> names = new List<string>();
collection.GetResourceNames(names);
Defensive patterns

Strategy: validation

Validate before calling

if (results == null) results = new List<string>();
collection.GetResourceNames(results);

Type guard

bool IsValidResults(List<string> results) => results != null;

Try / catch

try { collection.GetResourceNames(results); } catch (GameFrameworkException ex) { Log.Error(ex.Message); }

Prevention

When it happens

Trigger: Calling collection.GetResourceNames(null) or with a List<string> variable that is null at call time.

Common situations: Forgetting to instantiate the list before the call; passing the return of another method that returned null; refactoring from an API that returns a list to this fill-in-place API.
