Data table helper is invalid.

Error message

Data table helper is invalid.

What it means

Thrown by DataTableManager.SetDataTableHelper when the supplied IDataTableHelper is null. The helper creates DataTableBase instances by type, so a null value breaks the whole data table module and is rejected at setup time.

Solutions

1. Construct a concrete IDataTableHelper implementation and pass it.
2. Add the SetDataTableHelper call to the standard framework initialization sequence.
3. Check the helper instantiation for null-returning factory calls.

Example fix

// before
dataTableManager.SetDataTableHelper(null);
// after
m_DataTableHelper = new DataTableHelper();
dataTableManager.SetDataTableHelper(m_DataTableHelper);

if (helper != null) dataTableManager.SetDataTableHelper(helper);

bool IsValidTableHelper(IDataTableHelper h) => h != null;

try { dataTableManager.SetDataTableHelper(helper); } catch (GameFrameworkException ex) when (ex.Message.Contains("Data table helper")) { /* register helper */ }

When it happens

Trigger: Calling SetDataTableHelper(null), or passing a helper variable that was never assigned.

Common situations: Game entry code missing the helper registration step; refactor deleted the instantiation; wrong component wired in the framework startup list.
