Assitant module freezes after some use (Uncaught TypeError)

[E3V3A]

After having my assistant put to test, it suddenly froze while recording.

Uncaught TypeError: Cannot read property 'dismiss' of null
I'm not sure which alert.js this come from.

Here is a screenshot:

This might be related to #12.

This may be related to #9...

Not sure if related, but I found this in the error log in the updated version when frozen.

[ASSTNT] Conversation Error: { Error: Service unavailable.

The code generating the log message is:

        .on('error', (error) => {
          console.log('[ASSTNT] Conversation Error:', error);
          record.stop()
          this.sendSocketNotification('ERROR', 'CONVERSATION')
        })

Another error that arrived today out-of-the-blue, while using Google.

I have no fcuking idea what this means!
Anyone else seen this?

If this has anything to do with this module, then line 259 is here:

      conversation
        .on('audio-data', (data) => {
          //record.stop()
          const now = new Date().getTime()
          if (mode == 'ASSISTANT') {
            this.sendSocketNotification('MODE', {mode:'ASSISTANT_SPEAKING'})
            speaker.write(data);             //   <<=== ERROR LINE =================== 
            spokenResponseLength += data.length;
            const audioTime = spokenResponseLength / (this.config.assistant.conversation.audio.sampleRateOut * 16 / 8) * 1000;
            clearTimeout(speakerTimer);
            speakerTimer = setTimeout(() => { speaker.end(); }, audioTime - Math.max(0, now - speakerOpenTime));
          } else {

The original error is coming from Line 133 in alert.js of the default Alert module of MM:

	hide_alert: function(sender) {
		//Dismiss alert and remove from this.alerts
		this.alerts[sender.name].dismiss();  // <<========= LINE  113 !
		this.alerts[sender.name] = null;
		//Remove overlay
		var overlay = document.getElementById("overlay");
		overlay.parentNode.removeChild(overlay);
},

I have filed an issue here.

note:

• all modules are receiving and handling SHOW_ALERT and HIDE_ALERT...
• /var/log/auth.log has some mysterious message:
  systemd-logind[351]: Removed session c30.

EDIT: systemd seem to com from cron...

EDIT2: This comment invalid.

This was fixed in MM PR: MagicMirrorOrg/MagicMirror#1248

The other issues now seem unrelated to OP. (Open new issue for those if they re-occur.)

PS. To fix this while MM dev PR is being considered, fix yourself with:

    hide_alert: function(sender) {
        //Dismiss alert and remove from this.alerts
        if (this.alerts[sender.name]) {
            this.alerts[sender.name].dismiss();
            this.alerts[sender.name] = null;
            //Remove overlay
            var overlay = document.getElementById("overlay");
            overlay.parentNode.removeChild(overlay);
        }
    },
