INVALID_STATE_ERR is causing the device to CRASH #23
Description
I am using this library for connecting to the MQTT sever. I am getting the INVALID_STATE_ERR. I am not able to replicate the error. How to handle this type of error?
I am pasting my error stack here
com.facebook.react.common.JavascriptException: INVALID_STATE_ERR, stack:
value@79:1340
_socket_send@557:21101
_on_socket_open@557:16408
<unknown>@557:628
value@63:1501
<unknown>@79:4566
value@32:1363
value@18:3559
<unknown>@18:1044
value@18:2986
value@18:1016
I am using socket only for receiving the message. Can any one help regarding this?. I am attaching my Code Snippet
// These are my Utility function.
_createClient (options) {
const location = this._getLocation()
const clientId = this.generateClientId()
const port = this._getPort()
const path = this._getPath()
const client = new Paho.MQTT.Client(location, port, path, clientId)
console.log('Connecting to client', location, port, path, clientId)
this.client = client
this.client.onMessageArrived = this._notifyListeners // in case of new Message Arrival
this.client.onConnectionLost = this.retry
return this.client
}
initialize (cb) {
return new Promise((resolve, reject) => {
try {
this._createClient()
this.observers = []
if (!this.connected) {
return this.connect()
.then(resolve)
.catch(err => {
reject(new SocketError(err))
})
} else {
console.log('Already Connected')
return Promise.resolve()
}
} catch (ex) {
return reject(new SocketError(ex))
}
})
}
subscribe (subscribeTopic) {
return new Promise((resolve, reject) => {
try {
if (this.connected) {
console.log('Subscribing for Topic', subscribeTopic)
this.client.subscribe(subscribeTopic, {
onSuccess: () => {
return resolve()
},
onFailure: err => reject(new SocketError(err)),
qos: 2
})
} else {
return reject(
new SocketError(
'Unable To Connect to socket. Exponential BackOff Started'
)
)
}
} catch (ex) {
return reject(new SocketError(ex))
}
})
}
For connecting I am using -
MQTTSocket.initialize() .then(() => MQTTSocket.subscribe(_userId))
_userId is the userId.
How can i replicate the issue?.
