Server-Side Code in Monday Apps – Upload Fails

Hi everyone,

I’m currently building a Monday App and trying to use server-side nodejs functions to:

  • Make REST calls to an external API from the frontend

  • Receive webhooks from that API

  • Upload a signed file back into Monday

Ideally, I want to host these functions directly using the serverless functions feature provided by the Monday Apps Framework.

The Problem

I’m already running into issues when trying to upload even a minimal function. For example, with this simple function:

module.exports = async function (req, res) {
  res.json({ message: "Hello from server" });
};

and the following mapps.config.js configuration:

module.exports = {
  functions: [
    {
      name: "testFunction",
      entry: "./functions/testFunction.js",
      runtime: "nodejs20.x",
      events: [
        {
          eventType: "http",
          method: "GET",
          path: "/api/test"
        }
      ]
    }
  ]
};

I consistently get this error when deploying:

✖ There was an error deploying the application.

Unfortunately, I can’t find any working examples or detailed error messages to help me debug this.

My Questions

  1. Is there a working example of a minimal server-side function for Monday Apps?

  2. Does the function need to meet specific requirements (e.g. headers, response format)?

  3. Is an index.js file required for server-side functions?

  4. Are there known limitations or issues with deploying via mapps code:push?

  5. Is it even possible to receive webhooks via http events and then upload files to Monday?

  6. Can the entire flow — REST communication with an external API and webhook handling — be fully hosted within Monday?

I’d really appreciate any tips, examples, or insights to help get this working.

Thanks in advance!
