ZodError gets empty path

[ivan-kleshnin]

Setup

const searchLocations = makeEndpoint({
  method: "get",
  path: "/locations",
  response: z.array(z_location), // validation rules don't matter here
  parameters: [{
    name: "search", // !!!
    type: "Query",
    schema: z.string().min(1),
  }],
  errors: z_defaultErrors,
})

export default makeApi([
  searchLocations,
])

GET http://localhost:3001/locations?search=

400 Bad Request 👌

{
    "context": "query.search",
    "error": [
        {
            "code": "too_small",
            "minimum": 1,
            "type": "string",
            "inclusive": true,
            "exact": false,
            "message": "String must contain at least 1 character(s)",
            "path": [] -- 😨
        }
    ]
}

Explanation

Without a clear reason error[0].path is empty and path data is reexposed at context. Might be changed at #76.

I expected path value to be ["query", "search"]. Libraries that parse Zod errors (like https://github.com/causaly/zod-validation-error and others) obviously rely on path so I have to manually split context value and put it back to path...
I'm not sure if it's a bug or something intentional, please clarify 🙏

Hello it's not a bug. query search is not an object, that's why zodios adds some context information that is separate.
if you want zod to have a path for other error parsing tools, you can add a refine in your schema.
cf zod documentation about zod custom path :
