The response of a server action is purely based on the decision of the developer.
There is no more Response object in the server action, hence

The error handling depends on how you want to implement it.
You can return boolean and check the result client-side
or you can return data | string where data is your data object and string is your error code

I personally use react-hook-form to handle server errors as well as client-side navigation in one component. But i am yet to be sure how you would do it with pure React

you getting a cookie and do.something else

How do i access the value returned by the function

Like where is the value returned

Ill definitely check it out

Its where you call the server action :/

const data = serverAction()
then console.log(data) would be true if you return true

but its getting called inside form action

see thats why idk where the return went if its inside the action attribute.

You could use onClick and create a custom handler for it with react-hook-form

Yah thats the problem well thanks for the help ill try out the react hook form
