Possibility to get typescript error type in setGlobalMessage

[vladshcherbin]

Hey 👋

Wondering if it's somehow possible to get the correct typescript type from issue.type

setGlobalMessage((issue) => {
  switch (issue.type) {
    case 'min_length':
      // issue is of type MinLengthIssue so the issue.requirement is a number
      return `Please enter at least ${issue.requirement} characters`
    default:
      return issue.message
  }
}, 'en')

In the example above the type of issue.requirement is unknown

I've tried this way but it didn't work out:

I've also tried to find something like InferIssue<'min_length'> to pass error type there and it also didn't work out 😅

Theoretically this is possible, but there might be a problem if users use custom schemas and actions. I will have to think about it.

Please don't mark it as stale. I'll leave it open to see if more users want this feature in the long run. Please add a 👍 if you want this feature. Theoretically, this feature is possible, but it will probably cause problems if developers are using custom schemas and actions. It is unclear if we can support it, but I will investigate if many developers request it.
