sideEffect on useMutation not working
Hey, I am trying to update a state upon success of a useMutation, before I added the sideEffect itt was all working fine but when I implemented the onSuccess side effect I am getting error I posted below. postMessage is an asycn function I am exporting from another file. It takes 3 parameters sessionId, userId, input

which version are you on?

V5
I also had issues passing multiple parameters to the postMessage function
I need seed 3 arguments but only 1 is being sent

Yeah thought so. but how come into mutation function i can only send 1 argument?
I found a way around it. I am sending my arugments in a object like this mutation({param1: x , param2: y})
