[Bug] $randomActiveViewer sometimes returns as string instead of doing it's job

[Alastor-git]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Sometimes, $randomActiveViewer just appears in the message instead of returning a viewer name, at a time when there are active viewers.

My guess would be either an index out of bounds issue, or firebot sometimes forgets momentarily the active viewers list and it appears empty to the bot for an instant, although I can't access the logs to check more precisely (I'm not the streamer).

Expected Behavior

$randomActiveViewer should be replaced by a viewer name.

Steps To Reproduce

• Create a command using $randomActiveViewer.
• Have it used enough, by the looks of it

Version

5.52.0

What operating system are you using Firebot on?

Hello,

With regards to the request for information, the details had been provided in the associates discord thread.
I'm re-oppening this issue, because I have noticed it crop up again in the past few days.

Version : 5.53.2
other details remain unchanged.

The associated logs are :

It looks like the variable $randomActiveViewer returns Undefined for whatever reason. I can attest that there were active viewers at the time, so the list wasn't empty either.
So my guess would be a timing issue where it fails if the database is in the process of being updated, and a possible solution might be to make use of semaphores.
