Download failed Error: Got error 508 (Loop Detected) while fetching https://xxxxnovel.deno.dev/covers/novel-key.jpg

[waptik]

Hi. I'm building a telegram bot that's converting novels to epub using my own module. So i saved the covers locally inside a /static folder in my github project and serving them on request basic through oakjs.

When i test the bot locally, the epub file is being generated without any issue but i face some roadblock when i deploy the code base on deno deploy.

Here's the code for covers routing

.get("/covers/:key.jpg", maxAge30Days, async (ctx) => {
    const cover = `${ctx.params.key}.jpg`;

    await ctx.send({
      path: cover,
      root: `${Deno.cwd()}/static`,
      extensions: ["jpg"],
    });
  });

Here's a portion of the error from deno deploy logs
