Can't run test code using 0.31.0-rc

[chimame]

When I install the 0.31.0-rc version and try to run the test code using Vitest, I get the error

 SyntaxError: Invalid regular expression flags

I've created a minimal sample code that will cause this to happen here. The sample code simply outputs the valibot API string to the log. Of course, there is no error when using 0.30.0. Is there anything special I need to do from 0.31.0 onwards?

import { describe, it, expect } from 'vitest'
import { string } from 'valibot'

describe('sample', () => {
  it('should pass', () => {
    console.log(string) // <-- After deleting it, the test can be executed normally.
    expect(1 + 1).toBe(2)
  })
})

I know what the problem is. What JavaScript runtime and version are you using? If you are using Node.js, try running your code with >=v20.

Thank you for your quick response!

My Node.js version was 18.18.2. I changed it to 20.13.1 and the test ran normally. Does 0.31.0 support Node.js versions 20 or higher?

I have started to use an advanced regex feature to improve and simplify the emoji regex. Unfortunately, this is not supported in Node.js v18 or older.

Thanks for your answer! I'll keep in mind that supported versions of Node.js change.

If there are people who can't upgrade, I will reconsider this change and reschedule it for a later date. On the other hand, as far as I know, upgrading from v18 to v20 shouldn't cause any problems.

This is fixed in v0.31.0-rc.4
