Answer 1

I tried to recreate your issue, but it appears to validate as expected for me.

• ✅ 2023
• ✅ 2099
• ❌ 1999
• ❌ 2001
• ❌ 2100

The following code works for me:

{
  type: 'number',
  name: 'issue_year',
  label: 'year of issue',
  required: true,
  validate: (val) => {
    if (!val) return true;
    const pattern = /20[2-9][/\d]/g;
    return pattern.test(val.toString()) || 'invalid year of issue';
  },
}
