transport for file does not work in middleware.

[yaaasuu]

Hi, I try to export logs to the local file. But It does not work well.
When I set like the following and use "logger.info" in "/middleware.ts" , the log appear in the console only.
If I use "logger.info" in another place like "pages/api/auth/auth.ts" , the log appear in not only the console but also "./logs/app.log".

Do you have any way to export middleware logs?

const pinoConf = {
  level: "debug",
  transport: {
    targets: [
      {
        level: "info",
        target: "pino/file",
        options: { destination: "1" }, // stdout
      },
      {
        level: "info",
        target: "pino/file",
        options: {
          destination: "./logs/app.log",
          mkdir: true,
          sync: true,
        },
      },
    ],
  },
  timestamp: () =>
    `,"timestamp":"${new Date(Date.now()).toLocaleString("ja-JP", {
      timeZone: "Asia/Tokyo",
    })}"`,
  browser: {
    asObject: true,
  },
};
export const logger = pino(pinoConf);

middleware is like a browser environment (mostly because it has less capabilities than Node.js), therefore you are loading thr browser bundle instead.

I have no clue what the right bundling incantation you'd need to do to support this.

Thank you for replying.
I understand I have to another browser function instead of this library.
