What is actually happening?

I'm using nextjs 15 + tailwind 4 + webpack, all the obfuscator seems to be correct, but server action, which used to work normally, can't get the return value now, for example

const resp = await signInAction({email: refEmail.current.value, password: refPassword.current.value})

resp can get json return value before, now it is undefined.
