I'm getting an error while generating key after uploading file into IPFS infura.

Sample code given below

var ipfsAPI = require('ipfs-http-client');
const ipfs = ipfsAPI('ipfs.infura.io', '5001', { protocol: 'https' });
var oldpath = files[property].path;
var uploadedFile = fs.readFileSync(oldpath);
const filess = [{
                    path: files[property].name,
                    content: ipfs.types.Buffer.from(uploadedFile)
             }];
 ipfs.add(filess, function (err, files) {

                  if (err || !files) {
                        return reject('upload failed');
                    };
 var obj;
for (i = 0; i < data.length; i++) {
    obj = { "id": i, "hash": data[i], "EID": formFields.EID };
    tt.push(obj);
}
ipfs.dag.put(tt, {}, (err, cid) => {
    console.log(cid.toBaseEncodedString());
    const adr = cid.toBaseEncodedString();
    var dTimeStamp = new Date().getTime();
ipfs.key.gen(dTimeStamp, {
type: 'rsa',
size: 2048
}, (err, key) => {
    if (err != null) {
        console.log(err)
        }

    console.log("ipfs Key: ", key.id + " key name : " + key.name);

    var keyVall = key.id;


ipfs.name.publish(adr, { key: keyVall }, (err, pVal) => {


        console.log("published hash : " + pVal);

        var ipfsHash = pVal.name;


    return resp.json({ status: 'SUCCESS', message: 'user has been created successfully', digitalID: pVal });
});
});
});

});

i'm getting a following error while generating key

"SyntaxError: Unexpected token < in JSON at position 0

Any leads will be appreciated.

Infura IPFS service only allows a small set of IPFS API methods through their Gateway so you cannot generate a key via ipfs.key.gen

See Infura Documentation

I would recommend to run your own IPFS node, especially if you want to generate and store keypair.

  • thanks for the information. Do you have any documentation to run own IPFS node on windows server? – cmani2020 Jan 29 at 5:50
