Owner type is invalid.

Error message

Owner type is invalid.

What it means

FsmManager.HasFsm(Type ownerType) builds a TypeNamePair from the owner type to search its FSM registry. A null owner type would produce an invalid key, so GameFrameworkException('Owner type is invalid.') is thrown before the lookup.

Solutions

1. Pass a concrete typeof(OwnerClass) to HasFsm
2. Fix reflection code so the Type is resolved (or fail earlier) before the lookup
3. Validate the type argument at the boundary of your helper methods
4. Replace string-based type resolution with compile-time generics where possible

Example fix

// before
bool exists = fsmManager.HasFsm(ownerType); // ownerType may be null from reflection
// after
bool exists = ownerType != null && fsmManager.HasFsm(ownerType);

if (ownerType == null) throw new ArgumentNullException(nameof(ownerType));

bool IsValidOwnerType(Type ownerType) => ownerType != null;

try { bool exists = fsmManager.HasFsm(ownerType); } catch (GameFrameworkException ex) when (ex.Message == "Owner type is invalid.") { /* treat as not-found or fix type resolution */ }

When it happens

Trigger: Calling gameFrameworkFsmManager.HasFsm(null); passing a type variable obtained via reflection that failed to resolve.

Common situations: Reflection-based code where Type.GetType returned null for a misspelled type name; generic helpers forwarding a null typeof result; config-driven systems storing type names as strings.
