The entire code. Cc @Gaurav Chadha @Wimukthi

import parser from "co-body";
import typeis from "type-is";
import crypto from 'crypto';

const mimeTypes = {
  json: [
    "application/json",
    "application/json-patch+json",
    "application/vnd.api+json",
    "application/csp-report",
    "application/reports+json",
    "application/scim+json",
  ],
  form: ["application/x-www-form-urlencoded"],
  text: ["text/plain"],
  xml: ["text/xml", "application/xml"],
};

function isTypes(contentTypeValue, types) {
  if (typeof contentTypeValue === "string") {
    contentTypeValue = contentTypeValue.replace(/;$/, "");
  }
  return typeis.is(contentTypeValue, types);
}

function validate_signature(rawData, hmac_header, accessSecret) {
  const hmacReceived = hmac_header.replace('sha256=', '');
  const json_string = rawData.normalize('NFC'); // NFC Standardization
  const digest = crypto.createHmac('sha256', accessSecret).update(json_string).digest('hex');
  const resp = crypto.timingSafeEqual(
    Buffer.from(hmacReceived, 'hex'),
    Buffer.from(digest, 'hex')
  );
  console.log(

validate_signature: ${resp}

);
  return resp;
}

async function onExecution({ app_id, accessSecret }, { nodeReq, request, res, logging }) {
  try {
    logging.log(

onExecution

);

    const rawBody = await parser.text(nodeReq); // Read raw body as string
    const sig = request.headers['x-hub-signature-256'];
    logging.log("sig", sig);

    const valid = validate_signature(rawBody, sig, accessSecret);
    logging.log("valid", valid);
    if (!valid) {
      throw new Error("error validating signature");
    }

    return {
      request: {
        headers: request.headers,
        body: JSON.parse(rawBody),
      },
      output: {}
    };
  } catch (error) {
    logging.log(error);
    throw new Error(

error: ${error}

  }
}

export default {

Hi guys! cc @Gaurav Chadha @Wimukthi I modified this two lines:

const json_string = rawData.normalize('NFC'); // NFC Standardization
const rawBody = await parser.text(nodeReq); // Read raw body as string

I think the problem is here right?

// validate signature
function validate_signature(data, hmac_header, accessSecret) {
  const json_string = JSON.stringify(data);
  const hmacReceived = hmac_header.replace('sha256=', '');
  const digest = crypto.createHmac('sha256', accessSecret).update(json_string).digest('hex');
  const resp = crypto.timingSafeEqual(Buffer.from(hmacReceived, 'hex'), Buffer.from(digest, 'hex'));
  console.log(

validate_signature: ${resp}

)
  return resp;
}

Hi everyone! I'm getting this or the same error, but what's causing it are the words with accents. If I send the same message without accents it works. Can help?

I understood the error but I don't know how to adjust it. Whenever I send a message with an accent, the error is returned, if I write without an accent it works.

@Gaurav Chadha here is the doc https://docs.asaas.com/reference/create-new-customer Yes the dollar sign is part of the api key. I tried without $ using Postman and I got 401 (Unauthorized). I tried the same thing on Buildship hoping to get a 401 error and determine that the problem is the dollar sign, but I got the same error as before. Unexpected token '<', "<!doctype "... is not valid JSON

Giovanni Cocco - Hi everyone! I have a problem ...

I even created a new, simpler node with just the POST method for testing and still got the same error.

import fetch from 'node-fetch';

export default async function callApiPostMethod({
    url,
    access_token,
    name,
    cpfCnpj,
    email,
    mobilePhone
}) {
    const requestBody = {
        name,
        cpfCnpj,
        email,
        mobilePhone
    };

    const response = await fetch(url, {
        method: 'POST',
        headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/json',
            'Access_token': access_token
        },
        body: JSON.stringify(requestBody)
    });

    const data = await response.json();
    return data;
}
