Handle Server function Zod Validation Errors
Question for everyone using zod schemas as
validateInput how are you showing the errors into the actual UI? Because it seems like zod errors are actually serialized as string.9 Replies

do you mean
inputValidator ?vicious-goldOP•2mo ago
yes, using a server function inside a mutation lets say, the error we get its a "raw" string kind of, wondering whats a good DX to get the actual errors out of the functon so we can use in forms for example

you can add a custom serialization adapter that serializes zod errors

Is there any docs i can look into to add a custom serializer?

This is exactly what i needed @Manuel Schiller ! Thanks !!

when you have the adapter ready, please share

Well, im thinking if this should be the way, like the validation on TSR still throws a 500 on validation, should probably be a 400/409. Because this triggers errors on both server and client, for a validation error humm, thinking i should probably just validate inside the business logic itself.

@nikus I'm using a functiom middleware to catch the error,
setResponseStatus, and rethrow the error.
