I am using lotion js in my node js server, which is used as a blockchain technology. Some times I am getting Tendermint node crashed. As I am new to blockchain concept, I don't know the reason behind the crash.

I did not do any changes inside node modules

const admin = require("firebase-admin")

const db = admin.database()

let app = require('lotion')

({

  initialState: {count: 0}

})

function txHandler(state, tx, chainInfo) {

  state.count++

}

var port = process.env.PORT || 3000

app.use(txHandler)

app.listen(port)

db.ref('Deal').orderByChild('createdTime').startAt(Date.now())

.on("child_added", function(snapshot, prevChildKey) {

   var txnObject = {}

   txnObject.senderId = snapshot.val().senderId

   txnObject.name = snapshot.val().name

   txnObject.phoneNumber = snapshot.val().phoneNumber

   txnObject.receiverId = snapshot.val().receiverId

   txnObject.amount = snapshot.val().amount

  axios.post('http://localhost:' + port + '/txs', txnObject).then(function(response){

   console.log('saved successfully')

   }).catch(function(error) {

       console.log('failed to save')

       console.log(error)

  })

})

This is my index.js file content.

And the error I am getting is:

Users/chandrika/Documents/lotion-js/node_modules/supercop.js/lib.js:97

      throw ex;

      ^

Error: Tendermint node crashed

    at ChildProcess.tendermintProcess.on (/Users/chandrika/Documents/lotion-js/node_modules/lotion/lib/tendermint.js:90:13)

    at ChildProcess.emit (events.js:160:13)

    at maybeClose (internal/child_process.js:943:16)

    at Socket.stream.socket.on (internal/child_process.js:363:11)

    at Socket.emit (events.js:160:13)

    at Pipe._handle.close [as _onclose] (net.js:562:12)

Can anyone help me? Thank you in advance!

Hi,try using the following command in terminal:

$ rm -rf ~/.lotion

and then

$node index.js

This will forcefully remove the hidden file mentioned.
