Propagating errors in mutations in server actions

Helloooo. Recently, I have been thoroughly enjoying using

convex mutations

convex mutations

server-actions

server-actions

but I did run into something for which I would like some help. So lets say, my mutations throw a

ConvexError

ConvexError

, I have an async function in my

use server

use server

file (where all my

actions are

actions are

) where I call the convex mutation using

fetchMutation

fetchMutation

call - which is wrapped in a

try-catch

try-catch

- if there's an error I will try to

re-throw

re-throw

the error. I call this async function in another file (a react component, lets say) where I catch the

re-thrown error

re-thrown error

in a

toast

toast

but it doesn't give the same error message I threw from

backend

backend

using

ConvexError

ConvexError

and it gives me this instead:

An error occurred in the Server Components render

An error occurred in the Server Components render

which I think is because the

re-thrown error

re-thrown error

cannot be serialized. Does anyone know a way around this or have a better solution?
