Could not find internal type UnityEditor.LogEntry during Get

Error message

Could not find internal type UnityEditor.LogEntry during GetConsoleEntries.

What it means

Thrown by GetConsoleEntries when the internal Unity type 'UnityEditor.LogEntry' cannot be resolved via reflection from the EditorApplication assembly. The console reading pipeline depends on this internal type to instantiate log entry objects for GetEntryInternal. If Unity renames, moves, or removes this internal type, the reflection lookup fails.

Solutions

1. Check if a newer version of MCP for Unity adds support for your Unity version (the LogEntry reflection paths are version-specific).
2. Report the Unity version to the MCP for Unity maintainers so the reflection cache can be updated.
3. As a workaround, use Unity's 'clear_console' or rely on log files instead of the console API.
4. Downgrade or switch to a supported Unity LTS version if console reading is critical.

// C# — pre-check the type exists before the hot path
Type logEntryType = typeof(EditorApplication).Assembly.GetType("UnityEditor.LogEntry");
if (logEntryType == null)
    return new ErrorResponse($"LogEntry type not found in Unity {Application.unityVersion}. Console reading unsupported on this version.");

try
{
    var entries = GetConsoleEntries(pageSize, cursor, ...);
}
catch (Exception ex) when (ex.Message.Contains("Could not find internal type UnityEditor.LogEntry"))
{
    // Fall back to reading Editor.log or return an unsupported-version message
    return new ErrorResponse($"Console reading not supported on Unity {Application.unityVersion}.");
}

When it happens

Trigger: Calling read_console on a Unity version where 'UnityEditor.LogEntry' was renamed or moved to a different assembly/namespace. This is an environment/version issue, not a user input error.

Common situations: Unity 6.x or a preview/beta version changed internal LogEntry internals; running on a stripped or modified Unity build; the type was split or its accessibility changed.
