I am trying to deploy my express.js app but i keep facing this error

Runtime.UserCodeSyntaxError: SyntaxError: Cannot use import statement outside a module
    at _loadUserApp (file:///var/runtime/index.mjs:1084:17)
    at async UserFunction.js.module.exports.load (file:///var/runtime/index.mjs:1119:21)

netlify/functions/server.js:

import serverless from "serverless-http";
import app from "../../index.js";

export const handler = serverless(app);

I dont understand why it happens, my package.json uses "type": "module" and this is my netlify.toml:

[functions]
  node_bundler = "esbuild"

[build]
  functions = "netlify/functions"
  node_bundler = "esbuild"

[[redirects]]
  force = true
  from = "/*"
  to = "/.netlify/functions/server"
  status = 200

Can’t say without a repo. Feel free to share one.
