Error: self signed certificate in NodeJS HTTPS Request - node.js

Question

I'm fairly new to NodeJS and I'm trying to implement HTTPS request from NodeJS (backend) directly to a middleware api hosted in IISNode with a GoDaddy certificate. I have another repo for my view (frontend) and all the calls to the middleware api through the browser are working with the GoDaddy certificate. The calls work fine with HTTP using Axios. When making the call to the middleware api with HTTPS from the NodeJS backend I'm getting:
Error: self signed certificate
at TLSSocket.onConnectSecure (_tls_wrap.js:1058:34)
at TLSSocket.emit (events.js:198:13)
at TLSSocket.EventEmitter.emit (domain.js:448:20)
at TLSSocket._finishInit (_tls_wrap.js:636:8)
It's really weird that the frontend repo communicates with no issue to the middleware via the browser but the NodeJS backend calls will not. I have tried using Axios in the backend with no luck and cert errors. I switched to HTTPS and the GET calls are working, but POST calls give me the error above.
I have read tons of posts and examples regarding self-signed certs but I'm using a cert that is generated from GoDaddy. Here are some code snippets I've tried:
Axios:
const SSLAgent = new https.Agent({
rejectUnauthorized: true,
passphrase: process.env.PASSPHRASE,
pfx: fs.readFileSync(path.join(__dirname, "../../") + process.env.PFX),
ca: fs.readFileSync(path.join(__dirname, "../../") + process.env.CRT_BUNDLE)
});
const fetchData = () => axios.get(`${process.env.MIDDLE_WARE_URL}/something`, {
headers: {
Authorization: `Bearer ${token}`
},
httpsAgent: SSLAgent
});
const uploadData = () => {
const form = new FormData();
form.append("data", fs.createReadStream(dataPath));
return axios.post(`${process.env.MIDDLE_WARE_URL}/data`, form, {
headers: {
...form.getHeaders(),
Authorization: `Bearer ${token}`
},
httpsAgent: SSLAgent
});
};
const fetchItemImage = (ItemID: number) => axios.get(`${process.env.MIDDLE_WARE_URL}/item/${ItemID}/image.png`, {
responseType: "arraybuffer",
headers: {Authorization: `Bearer ${token}`},
httpsAgent: new https.Agent({pfx: fs.readFileSync(path.join(__dirname, "../../") + process.env.PFX), passphrase: process.env.PASSPHRASE}), ca: fs.readFileSync(path.join(__dirname, "../../") + process.env.CRT_BUNDLE)
});
HTTPS:
const SSLAgent = {
rejectUnauthorized: true,
passphrase: process.env.PASSPHRASE,
pfx: fs.readFileSync(path.join(__dirname, "../../") + process.env.PFX),
ca: fs.readFileSync(path.join(__dirname, "../../") + process.env.CRT_BUNDLE)
};
const middleServer = express;
const middle = express.Router();
https.createServer(SSLAgent, middleServer).listen(443);
let data;
const dataOptions = {
headers: {
"Authorization": `Bearer ${token}`
}
};
const fetchData = () => middle.get("/data", (req, res) => {
console.log("The req is: ", req);
if (res.statusCode === 200) {
console.log("The Fetch Data Res: ", res);
data = res;
}
data = [];
});
const uploadStuff = () => {
const form = new FormData();
form.append("Stuff", fs.createReadStream(stuffPath));
const stuffOptions = {
headers: {
...form.getHeaders(),
"Authorization": `Bearer ${token}`
},
form
};
return middle.post("/stuff", (req, res) => {
req.params(stuffOptions);
res.on("data", () => {
console.log("The post response is: ", res);
});
res.on("error", (error) => {
console.log("The post error is: ", error);
});
});
};
