Error handling in server actions when same action is used by both client and server

[Undistraction]

Summary

I am a little confused as to the correct way to handle errors that occur within server actions. If I have a server action, for example doSomethingAction that is used by both server components and client components, how should that action deal with errors, given that:

When called from the server, it can be wrapped in a try/catch:

try {
   doSomethingAction()
} catch {
   ...handle error
}

But when called from a client component it cannot be wrapped with a try/catch and needs to communicate the error through the response object:

const response = doSomethingAction()

if(response.error) {
   ...handle error
}

Given these two different requirements (depending on where the actions is used), it seems that the same server action cannot be used on both client and server. Is this correct or am I missing something>?
