Message is redundant with literals

[Wykaz]

Is there a way to make literal z.union responses less redundant ?

For example:

z.object({
    DEBUG: z.union([
        z.literal("0"), z.literal("false"),
        z.literal("1"), z.literal("true")
    ]),
});

if I don't pass the "DEBUG" field or if I put a invalid value, it returns:

Validation error: Invalid literal value, expected "0" at "DEBUG", or Invalid literal value, expected "false" at "DEBUG", or Invalid literal value, expected "1" at "DEBUG", or Invalid literal value, expected "true" at "DEBUG"

I would have seen something that looked like this:

Validation error: Invalid literal value, expected "0", "false" "1" or "true" at "DEBUG"
