[SOLVED] File upload by public is disabled with node js

Moralis General
#1

Hi!

I have this node js server that runs, atm locally, but will run on heroku/moralis (still to be decided). It has no front-end but executes code to upload a file to ipfs upon contract events.

It works like so: token gets minted > cloud function saves the event > nodejs gets triggered upon new record entry.

Code is as follows:

const Moralis = require("moralis/node");

Moralis.initialize = "MY-APP-ID"
Moralis.serverURL = "MY-SERVER-URL"
const btoa = function (str) {
  return Buffer.from(str).toString("base64");
};

init = async () => {
  console.log("I have been summoned!");
  let query = new Moralis.Query("NewTokenMints");
  let subscription = await query.subscribe();
  subscription.on("create", onTokenMint);
};

onTokenMint = async (token) => {
  console.log("New Token Minted!");
  console.log(token.attributes.tokenID);
  const metadata = {
    name: "A collection of Kekws",
    Id: token.attributes.tokenID,
  };

  const metadataFile = new Moralis.File(token.attributes.tokenID + ".json", {
    base64: btoa(JSON.stringify(metadata)),
  });
  await metadataFile.saveIPFS();
  console.log(metadataFile.ipfs());
};

init();

But when doing the save to ipfs function it gives the following error:

(node:41668) UnhandledPromiseRejectionWarning: Error: File upload by public is disabled.

Anyone know how to fix this issue?

Usually this error means that you are not authenticated

Error using "await metadataFile.saveIPFS({useMasterKey:true})"
#3

Hmm, how do I authenticate? In the moralis.initialize(“appid” , “”, “master key”)? This still gives the same error

#4

you could try to use await metadataFile.saveIPFS({useMasterKey:true});

This worked, thanks!

#6

how are you hiding the master Key ?

#7

you don’t have to hide it when you run cloud functions, in front end you should not use the master key

I also get the same error:
Here’s my code:

    const image = "data:image/png;base64," + btoa(svgData);

    Moralis.initialize(
        MORALIS_APP_ID, 
        "",
        MORALIS_MASTER_KEY
    );
    const file = new Moralis.File(
        "smolrunners_" + String(supply) + ".svg", 
        {base64 : image }
    );
    await file.saveIPFS({useMasterKey:true});

Can anyone tell me how to fix this issue?

#9

i used it then also it is showing me same error

#10

did you try with await file.saveIPFS(null, {useMasterKey:true}); ?

#11

yes i did.
can i show my code so you can help me

#12

you can use uploadFolder from web3api directly too in order to upload to IPFS

const Moralis = require(“moralis/node”);
const express = require(‘express’);
const multer = require(‘multer’);
let storage = multer.memoryStorage()
const upload = multer({storage: storage , dest: ‘uploads/’});

const router = express.Router();

const serverUrl = “…”;

const appId = “…”;

const masterkey = “…”

Moralis.start({ serverUrl, appId, masterkey});

router.post(’/get_and_convert’,upload.single(‘file’), async (req,res) => {

const imagestring = await uploadimage(req.file);

console.log(imagestring);

const imagefiles = new transaction({

     image : imagestring,

})

 

try {

    const dataToSave = await imagefiles.save();

    res.status(200).json(dataToSave)

}

catch (error) {

    res.status(400).json({ message: error.message })

}

})

uploadimage = async(fileobj) => {

const fileType = fileobj.mimetype;

const value = fileType.substring(fileType.lastIndexOf(`/`) + 1);

const imageFile = new Moralis.File(`myNFT.${value}`, {base64 : fileobj.buffer.toString("base64")});



await imageFile.saveIPFS(null,{useMasterKey: true});

imageURI = imageFile.ipfs();

console.log(imageURI);

}

what is issue because of which i am getting that error

#15

Please let me know a early as possible

#16

please check here on how to post code on forum:

#17

can you please check once the code.

#18

this works fine for me:

const Moralis = require('moralis/node')
const serverUrl = 'https://23423:2053/server'
const appId = '5234'
const masterKey = '523425'


async function x() {
  await Moralis.start({serverUrl: serverUrl, appId: appId, masterKey: masterKey})


    const imageFile = new Moralis.File("test_file", {base64 : "iVBORw0KGgoAAAANSUhEUgAAABgAAAAYCAYAAADgdz34AAAABHNCSVQICAgIfAhkiAAAAAlwSFlzAAAApgAAAKYB3X3"});
    f = await imageFile.saveIPFS({useMasterKey: true});
    console.log(JSON.stringify(f))
}

x()

if you run that code, you can see the output and you can find out after that how to get the url for ipfs
