Hello all,
I have been stuck with this error for a few days and have reached the end of my rope. I am brand new to AWS so I apologize if this is an obvious solution.
I am building a simple react app that calls my API Gateway sending a POST with the endpoint /submit-form
I get 200 status code for the preflight CORS and the same 200 for the request in devtools but return JSON of a 404 in Lambda/Dev tools console
I'm not sure if this is necessary but I did zip my lambda function with my node_modules
Response
{
"statusCode": 404,
"headers": {
"x-powered-by": "Express",
"access-control-allow-origin": "*",
"content-security-policy": "default-src 'none'",
"x-content-type-options": "nosniff",
"content-type": "text/html; charset=utf-8",
"content-length": "139"
},

"body": "<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n<meta charset=\"utf-8\">\n<title>Error</title>\n</head>\n<body>\n<pre>Cannot GET /</pre>\n</body>\n</html>\n"
}
Lambda Function
const express = require("express");
const serverless = require("serverless-http");
const cors = require("cors");
const fs = require("fs");
const OpenAI = require("openai").default;
const pdfService = require("./service/pdf-service");
require("dotenv").config({ path: ".env.local" });
const app = express();

// Middleware

app.use(express.json());

app.post("/submit-form", async (req, res) => {

console.log(formData);
