I have set up as per the steps listed above.
I have an RTM Token Generator and am placing the generated token in this._token = '' as listed in the code sample below.
Receving an error as follows. RTM:ERROR Error Code 5. Signature verification failed
export default class RTMClient {
constructor () {
this._client = AgoraRTM.createInstance(appID)
this._uid = ''
this._token = '' // token placed here after generating
this._invitation = null
this._remoteInvitation = null
this.eventBus = new EventEmitter()
//This status is used to control whether the phone can be accessed
//The 'onLine' is ok.
this.status = 'offLine' //onLine, offLine, calling, meeting
this.peerInvitation()
}
