Solutions

1. Construct AutoBossParam with boss and strategy settings before calling.
2. Null-check in JS before invoking.

Example fix

// before (JS)
dispatcher.RunAutoBossTask(param); // null -> throws

// after (JS)
const bossParam = new AutoBossParam(strategyPath);
dispatcher.RunAutoBossTask(bossParam);

// JS side
if (!param) throw new Error('AutoBossParam is required');
dispatcher.RunAutoBossTask(param);

// JS
function isAutoBossParam(v) { return v != null && typeof v === 'object'; }

When it happens

Trigger: JS calls `dispatcher.RunAutoBossTask(null)` or passes an undefined variable.

Common situations: Author forgot to build AutoBossParam. Refactor left the param unset.
