callback is not a function error when using SyntheticMutator.update
I'm following the Synthetic mutation example in the documentation. But whenever I call on SyntheticMutator.update(), I'm getting this error

Your application is crashing. Waiting for file change.
Here are the calls done within my method call. When these lines were commented, there were no errors
if (status) {
SyntheticMutator.update(SupportUsers, ticketId, {
$addToSet: {
currentlyTyping: this.userId
}
});
} else {
SyntheticMutator.update(SupportUsers, ticketId, {
$pull: {
currentlyTyping: this.userId
}
});
}
Same issue for me with SyntheticMutator.insert. I suppose that Vent can also be used to emulate the writes, but it requires syncing data from multiple subscriptions on the client which is not really ideal.
@theodorDiaconu, can you give a clue on what we should be looking at to be able to fix this?
It's because channel variable here is an array while it should be a string. This is the line that causes that bug.
@dovydaskukalis thanks for tracking down where the error was coming from, I created a PR to fix it which is working on my local computer.
@dovydaskukalis were you able to make this work?
Yes, we also need to pass _id to _extractChannels() for it to work properly like in this PR https://github.com/cult-of-coders/redis-oplog/pull/358
