Could not update task status: ${error instanceof Error ? err

Error message

Could not update task status: ${error instanceof Error ? error.message : String(error)}

What it means

TaskExecutionService.startTask attempts to set the task status to 'in-progress' before execution. If updateTaskStatus fails, the error is caught and logged with this warning; execution continues because status updates are considered non-critical. This is a logged message, not a thrown error.

Solutions

Verify the parent task ID exists in the current tag before starting execution
Check write permissions on .taskmaster/tasks/tasks.json
Re-authenticate or restore connectivity if using the remote backend
Ignore if acceptable — execution proceeds; run updateTaskStatus manually afterwards

Defensive patterns

Strategy: try-catch

Validate before calling

const task = await tmCore.tasks.get(parentId).catch(() => null);
if (!task) console.warn(`Task ${parentId} not found; status update will be skipped`);

Type guard

function canUpdateStatus(task) {
  return task != null && typeof task.id !== 'undefined' && task.status !== 'in-progress';
}

Try / catch

// library already catches this; on the caller side:
const result = await executionService.start(taskId);
if (result.statusUpdateFailed) {
  console.warn('Status not updated; run taskService.updateTaskStatus manually');
}

Prevention

Verify the task ID exists in the active tag before starting
Ensure .taskmaster task files are writable
Re-authenticate when using the remote backend
Treat the warning as non-fatal but run a manual status sync afterwards

When it happens

Trigger: Calling startTask (via start) with options.updateStatus enabled and dryRun false when taskService.updateTaskStatus(parentId,'in-progress') throws — e.g. invalid parentId, task file locked/missing, or API failure in remote mode.

Common situations: Running task execution against a stale task ID; read-only task file; offline remote-backend usage; tag not found for parentId.
