errorFormatter returns invalid openapi schema

[matannahmani]

I've been using errorFormatter to include Zod errors and more custom errors, but the returned error type in openapi schema doesn't synchronize trpc error formatter:

    errorFormatter({ shape, error }) {
        return {
            ...shape,
            data: {
                ...shape.data,
                errCode: error.cause instanceof CustomTRPCError ? error.cause.errCode : null,
                zodError:
                    error.code === 'BAD_REQUEST' &&
                        error.cause instanceof ZodError
                        ? error.cause.flatten()
                        : null,
            },
        };
    }

return open-api schema:

{
  "message": "string",
  "code": "string",
  "issues": [
    {
      "message": "string"
    }
  ]
}

real response:

{
  "message": "Input validation failed",
  "code": "BAD_REQUEST",
  "issues": [
    {
      "validation": "uuid",
      "code": "invalid_string",
      "message": "Invalid uuid",
      "path": [
        "keyRingKeyId"
      ]
    }
  ]
}

I would suggest adding an option to override errorResponseObject with your own error object

Hello,

Any news on this topic ?

I'm having a use case where I try to add some data to a 409 error (the conflicting object). I cannot find a way to return anything attached to the error.

[cgyrock]

unfortunately，they hard code the condition，while zodError occur，force set message as ‘Input validation failed’

we can just change “error.caus.name” to break the condition.

I had tried it works!

is there even a reason to limit the shape of the response body? I think that's the purpose of the trpc errorFormatter that we're all using, I think trpc-openapi should just take the error object as it is and pass it on...
