When performing validation is it possible to preserve the errors array?

[TomppaPackage]

When using @tanstack/zod-form-adapter & ZodAdapter with Zod for Field-Level validation, the field.state.meta.errors array is concatenated into a single string.

Is it possible to preserve the original error array?

For instance, given the following schema;

const fullNameSchema = z
  .string()
  .min(12, { message: "Full name must contain at least 12 characters" })
  .refine((value) => value.startsWith("a"), {
    message: 'Full name must start with "a"',
  })
  .refine((value) => value.endsWith("b"), {
    message: 'Full name must end with "b"',
  })
  .refine((value) => value.includes("c"), {
    message: 'Full name must contain "c"',
  });

The output of fullNameSchema.safeParse('HelloWorld') will look like this;

[
    {
        "code": "too_small",
        "minimum": 12,
        "type": "string",
        "inclusive": true,
        "exact": false,
        "message": "Full name must contain at least 12 characters",
        "path": []
    },
    {
        "code": "custom",
        "message": "Full name must start with \"a\"",
        "path": []
    },
    {
        "code": "custom",
        "message": "Full name must end with \"b\"",
        "path": []
    },
    {
        "code": "custom",
        "message": "Full name must contain \"c\"",
        "path": []
    }
]

However, if using ZodAdapter, the output would be;

[
  'Full name must contain at least 12 characters, Full name must start with "a", Full name must end with "b", Full name must contain "c"'
]

I don't think so, because a validation can only return a ValidationError which is a string. However, you can access the issues array and transform the error message to your liking using the transformErrors function that is passed to the adapter.

e.g., just show one of the error messages.

 validatorAdapter: zodValidator({
    transformErrors: (e) => {
      return e?.[0]?.message
    },
  }),

It's true we can transform the resulting text, but in our use-case we present errors (when multiple) as a list.

I've found a workaround for the time being, which is to just add a clear separator in the transformErrors fn, and then split the resulting string by that separator to get an array of error strings.

This does however answer my question, that it's not a use-case currently supported by @tanstack/form, so I will mark this as answered. Thank you! :)
