drizzle-zod is not sending custom message upon validation

I have created the following loginValidationSchema which I call in a validateData middleware inside my routes. I was expecting the custom error message to be sent to user whenever the user does not provide a value but it is not working \ zod-schema

export const loginUserSchema = createSelectSchema(user, {
    email: (schema) =>
        schema.min(1, 'Email is required').email('Email must be valid'),
    password: (schema) => schema.min(1, 'Password is required'),
}).pick({
    email: true,
    password: true,
});

export const loginUserSchema = createSelectSchema(user, {
    email: (schema) =>
        schema.min(1, 'Email is required').email('Email must be valid'),
    password: (schema) => schema.min(1, 'Password is required'),
}).pick({
    email: true,
    password: true,
});

//Routes

 router.post('/login', validateData(loginUserSchema), loginUser);

 router.post('/login', validateData(loginUserSchema), loginUser);

//Middleware

 export default function (schema: AnyZodObject) {
    return (req: Request, res: Response, next: NextFunction) => {
        try {
            schema.parse(req.body);
            next();
        } catch (error) {
            if (error instanceof ZodError) {
                const message = error.issues.map(
                    (issue) =>
                        `${
                            typeof issue.path[0] === 'string' ? issue.path[0] : 'Unknown-path'
                        }: ${issue.message}`
                );
                res.status(400).json({ error: message });
                return;
            } else {
                throw error;
            }
        }
    };
}

 export default function (schema: AnyZodObject) {
    return (req: Request, res: Response, next: NextFunction) => {
        try {
            schema.parse(req.body);
            next();
        } catch (error) {
            if (error instanceof ZodError) {
                const message = error.issues.map(
                    (issue) =>
                        `${
                            typeof issue.path[0] === 'string' ? issue.path[0] : 'Unknown-path'
                        }: ${issue.message}`
                );
                res.status(400).json({ error: message });
                return;
            } else {
                throw error;
            }
        }
    };
}

When a user forgets to send email when using the login route, I was expecting the error message to be 'email: Email is required' but I am receiving 'email: Required' instead. Why is this happening?

I believe 'email: Email is required' happens only if the string doesn't have a minimum length of 1, not when the email is missing as a key. Basically, the difference between email: "" and email being undefined
