ValidationError.all throws TypeError with Zod validators #1482
Description
What version of Elysia is running?
1.4.11
What platform is your computer?
Darwin 25.0.0 arm64 arm
What environment are you using
bun v1.3.0
Are you using dynamic mode?
No
What steps can reproduce the bug?
- Create an Elysia server with Zod schema validation
- Add an
onErrorhandler that tries to accesserror.all - Make a request with invalid query parameters
import { Elysia, ValidationError } from "elysia";
import * as z from "zod";
const app = new Elysia()
.onError(({ error, code }) => {
if (error instanceof ValidationError) {
// This line throws TypeError with Zod validators
const errors = error.all;
return {
message: "Validation failed",
errors: errors,
};
}
})
.get(
"/test",
({ query }) => {
return { success: true };
},
{
query: z.object({
name: z.string(),
age: z.number(),
filters: z.object({
values: z.array(z.string()),
mode: z.enum(["include", "exclude"]),
}),
}),
}
)
.listen(3000);
console.log("Server running at http://localhost:3000");
### What is the expected behavior?
`error.all` should return an array of validation errors similar to TypeBox validators:
```typescript
[
{
summary: "Invalid input: expected number, received nan",
path: "/age",
value: "invalid",
},
{
summary: "Invalid input: expected object, received string",
path: "/filters",
value: "",
}
]This should work consistently across all validators (TypeBox, Zod, Valibot, etc.) since Elysia 1.4 added Standard Schema support.
What do you see instead?
The following error is thrown:
431 | Object.setPrototypeOf(this, ValidationError.prototype)
432 | }
433 |
434 | get all() {
435 | return 'Errors' in this.validator
436 | ? [...this.validator.Errors(this.value)].map(mapValueError)
