Function not getting a correct body

Heyo,

My function for some reason is suddenly failing. Trying it out with postman, the req.body should be filled, but it's not?

TL;DR

Issue: Function is failing because req.body is not being properly populated when testing with postman. Solution: Ensure that the function environment variables are correctly set up and that the request from postman includes the expected body content.

My function:

TypeScript

import { Client, Databases, Account } from 'node-appwrite';

export const client = new Client();
export const account = new Account(client);
export const databases = new Databases(client);

export default async ({ req, res, log, error }) => {
  client
    .setEndpoint(`${process.env.APPWRITE_API_URL}/v1`)
    .setProject(`${process.env.APPWRITE_PROJECT_ID}`)
    .setKey(process.env.APPWRITE_API_KEY);

  const document = req.body;

  if (!document) {
    error('Invalid request');
    return res.json({ ok: false });
  }

  try {
    await databases.getDocument('db_web', 'users', document?.userId);
    log('User document get');
  } catch (e) {
    if (e.code === 404) {
      try {
        log('Creating user document');
        const response = await databases.createDocument(
          'db_web',
          'users',
          document.userId,
          {},
          [
            `read(\"user:${document.userId}\")`,
            `update(\"user:${document.userId}\")`,
            `delete(\"user:${document.userId}\")`,
          ]
        );
        return res.send(200);
      } catch (e) {
        error(e);
        return res.send(500);
      }
    }
  }
  return res.send(200);
};
