This is not about plugin

[chrisui]

@hosseinmd Can we please re-open this? I've shown in the linked repro and issue that the issue only occurs when this plugin is used.

What is the issue if it is not this plugin?

You have syntax error. "ok" and "error" are function, they aren't type, we could add generic to function just when calling them, but for your use case change your code to this

type OkType = typeof ok;
type ErrorType = typeof error

const okStr: OkType<string> = ok
const errnum: ErrorType<number> = error
