Right side of assignment cannot be destructured

This may not be a solid issue but I am really confused. I did not have this problem when I was using vanilla Javascript; however, switching to solidjs changed a massive amount of how the app functions. So I am trying build a tauri app and I have a command:
async function new_session({ name, temp }) {
let msg;
if (name) {
msg = {
name: name,
temp: temp
}
} else {
msg = { temp: temp }
}
console.log({ "msg": JSON.stringify(msg) })
let check = await invoke("new_session", { "msg": JSON.stringify(msg) })
return check
}
async function new_session({ name, temp }) {
let msg;
if (name) {
msg = {
name: name,
temp: temp
}
} else {
msg = { temp: temp }
}
console.log({ "msg": JSON.stringify(msg) })
let check = await invoke("new_session", { "msg": JSON.stringify(msg) })
return check
}
This is the button that should execute that command:
<button
onClick={async (e) => {
e.preventDefault();
switch(selectedOption()){
case "temp_session":
let x = await new_session();
console.log("x: ",x);
break;
default:
console.log("choose a session");
};
console.log("selected option:", selectedOption());
}}

In vanilla javascript the command could be executed fine. However, I created a solid version so the app might be a little easier to reason through. All my commands got added to a commands.jsx file and the commands should get imported to get used. So i'm exporting the function from commands and importing it into the module I need to use it in. However, when I press the button that should execute it I get the error: Unhandled Promise Rejection: TypeError: Right side of assignment cannot be destructured I have absolutely no idea why it's broken, why it thinks it's destructuring something and how I might go about fixing it. Can someone give me some insight?

my guess: new_session({ name, temp }) has as signature {name, temp} but in the button you pass it nothing new_session() not sure why this would work in vanilla

Thank you for that. Definitely an oversight from copying it over. However, how would that lead to the error I'm receiving? I could see an error telling me that parameters are missing or something, but the error doesn't seem to line up with that. Just a bad error message? Unfortunately I won't have time to work on it until maybe tomorrow to test if that's the cause of the error.

well, I think you could reason about it like const { name, temp } = undefined typescript is handy for these type of stuff
function new_session({ name, temp }) {}
// is short hand for
function new_session(arg){
const { name, temp } = arg
}
function new_session({ name, temp }) {}
// is short hand for
function new_session(arg){
const { name, temp } = arg
}

That was the problem. Strange. Thanks. I should have seen that. I think what threw me was the error message which didn't seem to have anything to do with the actual error not providing parameters that are expected/required
