My understanding would be that you would do the same thing you would from the Redis CLI so key would be your key and value would be the field names and values you want to set so it would be something like the below.
That looks like a fix I did last year might still be needed, I always thought maybe it was just being used incorrectly as there were not many reports of it.
I will remake the PR and create a dev ticket for it now that I am on the n8n side
I was actually talking to @RicardoE105 about this one a while ago and a possible fix I put in place, It turns out it can be used by passing in an object. I don’t remember the exact details and I forgot to make a note of it but I will have another play later this week to try and remember.
As you can see, I’ve tried to follow this route, without success.
Running JSON.stringify on it beforehand also sadly doesn’t get us anywhere (just spits out that whacky array from earlier)
Can you share an example of what you are doing so I can give it a test? 0.236 is pretty old now as well so I would recommend upgrading when you get a chance.
