Vercel Cron任务仅部署时执行问题求助

我正在将Heroku上的部分Cron任务迁移到Vercel测试性能，目前遇到一个问题：从使用报告看Cron已触发，但代码并未实际执行，仅在部署变更时才正常运行。截图显示Cron按预期触发，但函数返回数据的时间与最后部署时间完全匹配。API地址：https://dw-router.vercel.app/api/pricefeed

API路由代码 #

//import type { VercelRequest, VercelResponse } from '@vercel/node';
import type { NextRequest, NextResponse } from 'next/server';
import { PriceFeed } from '@/lib/wharfsession';

export const revalidate = 0;
// GET for App Router, handler for Page Router
export async function GET(req: NextRequest, res: NextResponse) {
        console.log('---START---');
/*
        const authHeader = req.headers.get['authorization'];
        if (authHeader !== 'Bearer ${process.env.CRON_SECRET}') {
            return res.json({ success: false });
        }; */
        if ( req.method === 'GET' ) {
            try {
                const result = await PriceFeed(); //session.transact({ action: transferAction });

                //return res.status(201).json({ success: true, data: result });
                return Response.json({ success: true, data: result, status: 201 });
            } catch(err) {
                //return res.status(400).json({ success: false, data: err });
                return Response.json({ success: false, data: err, status: 401 });
            };
        } else {
            return Request.arguments;
        };
}

vercel.json配置 #

{
    "rewrites": [
        {"source": "/(.*)", "destination": "/"}
    ],
    "crons": [
        {
            "path": "/api/pricefeed",
            "schedule": "*/5 * * * *"
        }
    ]
}

package.json配置 #

{
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },
  "dependencies": {

    "next": "^14.1.0",

  },
  "devDependencies": {
    "@types/node": "^20.11.16",
    "@types/react": "^18.2.55",
    "typescript": "^5.3.3"
  }
}

疑惑点 #

• Cron是如何调用GET方法的？
• 为何Vercel不支持通用处理器，但官方Serverless API路由示例中却有相关内容？

我确定遗漏了某些配置，希望无需部署界面就能运行PriceFeed()函数，已经尝试过Vercel官方及社区的多种示例。项目处于生产环境，使用Pro计划。
