nodejs modio api "add modfile" failing to upload - node.js

Question

Im trying to upload modfiles with the api but it keeps saying that Im not including filedata. Ive tried with fetch like in the docs but it just gives the same error. If I try http it just gives a list of the files as if it was a GET request.
var zip = `./mod.zip`; // it exists!
var body = {
//filedata: `#${zip}`,
filedata: fs.readFileSync(zip, `binary`),
//filehash: crypto.createHash('md5').update(fs.readFileSync(zip, `binary`)).digest('hex'),
//version: version,
//active: active,
//changelog: changelog,
//metadata_blob: meta,
};
var res = await fetch(`https://api.mod.io/v1/games/${config.modio.gameid}/mods/${config.modio.modid}/files`, { // actually HTTP
method: 'POST',
headers: {
'Authorization': `Bearer ${config.modio.token}`,
'Content-Type': 'multipart/form-data',
'Accept': 'application/json',
},
body: JSON.stringify(body),
});
//console.log(body.filedata);
res = await res.json();
if (res.error)
console.log(res.error);
else
console.log(res);
{
"error": {
"code": 422,
"error_ref": 13009,
"message": "Validation Failed. Please see below to fix invalid input:",
"errors": {
"filedata": "The filedata field is required when upload id is not present.",
"upload_id": "The upload id field is required when filedata is not present."
}
}
}
Yes, ive submitted a bug report to them already, twice. Now they are ghosting me. (I'll probably submit a link to this as well)

Hi
As mentioned, you would need to send data using FormData, not JSON.
You can find details at https://developer.mozilla.org/en-US/docs/Web/API/FormData/Using_FormData_Objects
Thanks,

So, I remade my code
const https = require(`https`);
var crypto = require('crypto');
var FormData = require('form-data');
function ObjectToForm(obj = {}) {
var form = new FormData();
Object.keys(obj).forEach(key => {
var val = obj[key];
switch (typeof val) {
case `boolean`:
val = String(val);
break;
}
form.append(key, val);
});
return form;
}
if (fs.statSync(zip).size > 5368709120) return consolelog(`Zip bigger then 5gb`);
var body = {
filedata: fs.createReadStream(zip),
filehash: crypto.createHash('md5').update(fs.readFileSync(zip)).digest('hex'),
version: version,
active: active,
changelog: changelog,
metadata_blob: meta,
};
var form = ObjectToForm(body);
var options = {
hostname: 'api.mod.io',
port: 443,
path: `/v1/games/${config.modio.gameid}/mods/${config.modio.modid}/files`,
method: 'POST',
headers: {
'Authorization': `Bearer ${config.modio.token}`,
...form.getHeaders(),
'Accept': 'application/json',
},
};
var req = https.request(options, (res) => {
var data = [];
res.on('data', (d) => data.push(d));
req.on(`close`, () => {
var buffer = Buffer.concat(data);
var resp = JSON.parse(buffer.toString());
if (resp.error)
console.log(resp.error);
else if (res.statusCode == 201)
r(true);
});
});
req.on('error', (e) => {
console.log(`Error publishing:`);
console.log(e);
r(e);
});
form.pipe(req)
.on(`close`, () => req.end());
And it worked. Thanks King.
