Working in local but failed when deployed to vercel

[supermario12342003]

I tried this plugin using the following config

visualEditor({
      previewUrl: ({ locale }: PreviewUrlParams) => {
        return `${process.env.NEXT_PUBLIC_SERVER_URL}/${locale}/preview/pages`
      },
      collections: {
        pages: {
          previewUrl: ({ locale }: PreviewUrlParams) => {
            return `${process.env.NEXT_PUBLIC_SERVER_URL}/${locale}/preview/pages`
          },
        },
      },
    })

it's working in local, but it does not work in vercel. I got this error when it's trying to access api/me

the error disappears when i remove the plugin. Is it because this plugin does not support serverless environment?

The error is unfortunately not very informative. Are you able to pin it down to a more concrete error related to any of the plugin code?

for now i only know that this plugin works perfectly in a non edge runtime. i deploy it in render.com and heroku, they both work perfectly, but it can't run at cloudflare page nor vercel.
