Resource group ' ' is not exist.

Error message

Resource group '{0}' is not exist.

What it means

GetResourceGroupCollection resolves each name via GetResourceGroup; if no resource group with that name exists, the resolved group is null and this formatted GameFrameworkException is thrown naming the missing group. The collection cannot be built from a group that was never added.

Solutions

1. Use the exact resource group name defined in the resource configuration
2. Add the missing resource group before building a collection over it (AddResourceGroup)
3. Log available groups (GetAllResourceGroups) to find the correct name

Example fix

// before
var col = manager.GetResourceGroupCollection("UiRes"); // group is named "UIRes"
// after
if (manager.GetResourceGroup("UiRes") == null)
    manager.AddResourceGroup("UiRes", ...);
var col = manager.GetResourceGroupCollection("UiRes");

if (manager.GetResourceGroup(name) == null)
    throw new InvalidOperationException($"Resource group '{name}' does not exist; register it first.");

bool GroupExists(ResourceManager m, string name) => m.GetResourceGroup(name) != null;

try { var col = manager.GetResourceGroupCollection(names); }
catch (GameFrameworkException ex) when (ex.Message.Contains("is not exist")) { log.Error(ex.Message); /* prompt for correct group or add it */ }

When it happens

Trigger: Calling GetResourceGroupCollection with a name that was never created via AddResourceGroup / loaded resource list — e.g. a typo or a group defined only in a newer resource config version.

Common situations: Resource config updated on the server but the group name hardcoded in client code is stale; case-mismatch between the configured name and the lookup name.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
