How to get better error messages?
I have an union
z.union([z.literal('Conan'), z.literal('Jordan'), z.literal('Sona')]), when the value is not any of that, the default error message I get is Invalid literal value, expected "Conan", but I want it to say something like ...expected "Conan", "Jordan" or "Sona". How can I do that?Solution:Jump to solution
Hmm, I actually don't know the answer off the top of my head.
z.union is similar to z.object or z.array in that is a kind of "container" schema that runs the interior schemas and collects any errors.5 Replies

Hmm, I actually don't know the answer off the top of my head.
z.union is similar to z.object or z.array in that is a kind of "container" schema that runs the interior schemas and collects any errors.In this specific instance (of literal strings) you might find
z.enum easier to work with to get your desired outcome.
(You should actually get three errors for that particular union reporting the error reported by each schema.)I'm using
react-hook-form, and the errors are extracted from that, so maybe it sees one error and forget the other two?
Anyway you're right, I'm using z.enum and the message gets clearer
Invalid enum value. Expected 'Conan' | 'Jordan' | 'Sona', received 'Sonax'
Thanks a lotnp!
