Socket Hang up Error

Question

I was trying to store the new user on the multichain blockchain using streams before storing it to the database. I am getting socket error and when I am trying to store the new user using streams. 

I have setup the multichainOptions correctly and running the blockchain locally

{ Error: socket hang up
[0]     at createHangUpError (_http_client.js:313:15)

[0] User : undefined

******************************************* Here is the code 

const newUser = new User({

name: req.body.name,

email: req.body.email,

avatar,

password: req.body.password

});

const dataStr = JSON.stringify({

name: newUser.name,

email: newUser.email,

avatar: newUser.avatar

});

//multichain code goes here

multichain.publish(

{

stream: "users",

key: "prateek",

data: StrToHex(dataStr)

},

(err, info) => {

console.log(`User : ` + info);  # getting undefined here along with the error 

}

Please if anyone can help I am newbie to multichain and this is my first project using it. I am using multichain-node

Answer 1

Before using this library, we recommend trying the same operation with the multichain-cli command line tool. That will help you understand whether the issue is with MultiChain not being configured correctly, or else the library you are using.

Thanks a lot ! I solved it was just that I had to add autosubscribe key as streams to the multichain.conf file and it worked well for me. Thanks again !!
