form validation

[bihongbin3027]

After I started your example, Skills removed multiple choices, Submit removed disabled={!formik.dirty}, changed the validation rules skills: array().required('At least one skill is required'), and then click submit to submit the form, This form verification error is not displayed.

const validationSchema = object().shape({
username: string().required('Username is required'),
gender: string().required('Gender selection is required'),
country: string().nullable().required('Country is required'),
skills: object().nullable().required('At least one skill is required'),
birthdate: date().nullable().required('Birth date is required'),
interviewTime: mixed().required('Interview Time is required'),
})

const initialValues = {
username: '',
gender: 'Female',
country: null,
skills: null,
birthdate: null,
interviewTime: null,
}

@bihongbin3027 did you try an empty array on skills ?
