Not Possible to use Zod omit on schema passed to resolver

[blacksandsolutions]

Describe the bug

When omit is used to modify a schema, that schema causes an error when passed to zod resolver.

To Reproduce
I have a base schema for an Account.

export const AccountSchema = z.object({
    uid: z.string().uuid(),
    name: z
        .string({
            invalid_type_error: 'Please enter an account name.',
        })
        .pipe(nonempty),
    type: z.enum(['manual', 'auto'], {
        invalid_type_error: 'Please select a valid account type.',
    }),
})

For create form I extend this schema, omitting the uid

export const CreateAccountSchema = AccountSchema.omit({
    uid: true,
})

When the latter schema is passed to the resolver

I see this error when I try to submit / trigger form etc

If instead I pass AccountSchema like this, there is no error

I'm not able to create code sandbox using this template - it opens in a beta version and there are no files / edit controls..?

• Zod resolver Template

Expected behavior
Expect the Schema with omit applied to work the same as the original schema - e.g. not throw an error

• OS: Mac
• Browser: Chrome

I've worked around this by spitting my schema up into two parts.

export const BaseAccountSchema = z.object({
    uid: z.string().uuid(),
})

export const CreateAccountSchema = x.object({
    name: z
        .string({
            invalid_type_error: 'Please enter an account name.',
        })
        .pipe(nonempty),
    type: z.enum(['manual', 'auto'], {
        invalid_type_error: 'Please select a valid account type.',
    }),
})

export const AccountSchema = BaseAccountSchema.merge(CreateAccountSchema)

This way I can use the CreateAccountSchema in the form and AccountSchema wherever I need to validate the full object

I encountered this issue too, and my solution was quite similar to yours.

Here’s an example with the same context:

export const AccountSchema = z.object({
    uid: z.string().uuid(),
    name: z
        .string({
            invalid_type_error: 'Please enter an account name.',
        })
        .pipe(nonempty),
    type: z.enum(['manual', 'auto'], {
        invalid_type_error: 'Please select a valid account type.',
    }),
})

And then put the attribute to undefined...

export const AccountSchema = BaseAccountSchema.merge(z.object({ uid: z.undefined() }));

This workaround isn't perfect, but it was the best solution for my context. I wish omit worked out of the box.

Hi! Could you please provide a minimal reproduction using Codesandbox?
