Zod OpenAPI - Identify which request validator fails

[andrewjtorres]

Is there a way to identify which request validator (body, params, query, cookies, or headers) fails?

It appears all request validators leverage the same hook, either a route-specific hook or the defaultHook provided to the OpenAPIHono class when it was created.

I've currently implemented a workaround that utilizes zod error maps. Each request validator schema recieves a custom error map that adds a related prefix ([[body]], [[cookie]], etc.) to each of the validation errors. Then the defaultHook checks for the existence of those prefixes to determine which validator failed. This workaround is less then ideal since it takes a lot of configuration that is not enforcable and easy to mess up.

My hope is that someone has a native solution or a more ideal workaround. 🙂
